Abstract: A coil component includes an insulating layer; an annular ring-shaped coil core embedded in the insulating layer; a coil electrode wound around the coil core; an input electrode designed for external connection, disposed on a lower surface of the insulating layer, and connected to a first end of the coil electrode; and an output electrode designed for external connection, disposed on the lower surface of the insulating layer, and connected to a second end of the coil electrode. One of the input electrode and the output electrode is disposed inside the coil core in a plan view. With this configuration, unlike a conventional coil component in which both input and output electrodes are disposed outside a coil core, it is possible not only to easily reduce the area of the coil component in a plan view, but also to improve heat dissipation characteristics of the coil component.

At least one main surface of the pair of main surfaces includes a second surface region that is a region other than the first surface region.

Abstract: An inductor component includes an inductor electrode having two metal pins that form input and output terminals and a connecting conductor that connects one end of each of the metal pins to each other, the inductor electrode arranged such that other ends of the metal pins oppose each other, and a resin layer containing the inductor electrode such that other ends of the metal pins are exposed. The resin layer is formed having a single-layer structure. Variation in the characteristics of the inductor electrode can be reduced as compared to a case where the parts corresponding to the metal pins of the inductor electrode are formed as via conductors or through-hole conductors. Because the resin layer has a single-layer structure, stress acting on joint portions between the metal pins and the connecting conductor can be reduced, which makes it possible to improve the reliability of the inductor component.

The columnar bodies include a root connected to the flat plate, and a tip connected to the substrate. In a plan view of the electronic component module, the tip is not outside the root.

Abstract: A radiation conductor is constructed of a metal plate having a pair of main surfaces pointing in opposite directions. Each main surface of the pair of main surfaces includes a first surface region that includes at least part of a peripheral edge portion of the main surface. At least one main surface of the pair of main surfaces includes a second surface region that is a region other than the first surface region. A dielectric member holds the radiation conductor in such a manner that the first surface region of each main surface of the pair of main surfaces is sandwiched between portions of the dielectric member in a thickness direction of the radiation conductor. A housing supports and accommodates the dielectric member. The second surface region of the at least one main surface is exposed.

Abstract: A first resin layer (resin insulating layer) is formed by forming first and third covering portions in close contact with peripheral surfaces of respective end portions of first and second metal pins on the side closer to first end surfaces thereof, and by forming a body portion in a state of covering the respective surfaces of the first and third covering portions. Therefore, even when the first resin layer is thermally contracted, boundary regions of the one principal surface of the first resin layer around the respective end portions of the first and second metal pins on the side closer to the first end surfaces are filled with the first and third covering portions. Hence gaps can be prevented from being generated in those boundary regions, and a columnar conductor (first metal pin) can be avoided from deviating in position.

Abstract: Substrate-side wiring electrode patterns 16, which form a part of a coil electrode 12, are provided on a wiring substrate 20, and as a result reductions in the size and profile of a resin insulating layer 31, in which a coil core 11 is buried, can be achieved. Therefore, reductions in the size and the profile of a coil module 1 can be achieved compared with a coil module of the related art which is formed by mounting a coil component on a wiring substrate. In addition, since the substrate-side wiring electrode patterns 16, which form a part of the coil electrode 12, are provided on the wiring substrate 20, the heat generated by a coil 10 can be efficiently released from the substrate-side wiring electrode patterns 16 to the wiring substrate 20. Therefore, the heat dissipation property of the coil module 1 can be improved at low cost.
