Abstract: There are included a core 20 formed from a magnetic material; a terminal mounting unit 80 arranged on one end portion side of core 20; a coil 40 which is arranged on the outer circumferential side of core 20 and concurrently which is formed by winding a conductive wire 41; and a plurality of terminal members 70 which are mounted on terminal mounting unit and concurrently which are electrically connected with a terminal end of conductive wire 41 or with an electronic component at any position, wherein at terminal mounting unit 80, there are provided a plurality of mounting grooves 81 for plugging-in terminal members 70.

Abstract: Provided is an antenna coil component including a bobbin around which a winding is wound, a base provided at least at one end side of the bobbin, and one or more metal terminals each fixed to the base, at least one metal terminal among these metal terminals including a fixing part for fixing the metal terminal to the base, a mounting part provided at a position away from the fixing part, and a neck part for connecting the fixing part and the mounting part to each other. The neck part has a length in a direction substantially orthogonal to a direction from the fixing part to the mounting part and substantially parallel to surfaces of the mounting part, which is narrower than that of the mounting part. Provided as well are an antenna unit using the antenna coil component, and a method of manufacturing the antenna coil component.

Abstract: A capacitance type detection device may include a sensor electrode forming a capacitor with respect to a peripheral conductor; a measurement unit measuring the floating capacitance of the sensor electrode, which changes correspondingly to a positional relation between the sensor electrode and the detection object; and a judgment unit judging the approach of the detection object in a case in which there is satisfied an approach detection condition including a fact that a magnitude correlation between a time rate-of-change of the floating capacitance measured by the measurement unit and a predetermined time rate-of-change which is defined correspondingly to a combination of the detection object and an object to be discriminated so as to be different from the detection object lies in a predetermined relation.

Abstract: The present invention provides a coil component provided with a magnetic core and a coil wound around the magnetic core. The coil component of the present invention is provided with an eddy-current generation member using any one of or any combination of a tape member using a conductive metallic foil, a thin film using a conductive metal material, a ribbon using a conductive metal material, a coated film using a conductive metal material, and a plate member using a conductive metal material. In a coil antenna adopting the coil component of the present invention, it is enabled to adjust the Q value to a desired value without increasing the direct current resistance value.
