Abstract: In a multilayer coil component, a multilayer body includes a plurality of insulator layers and a through-hole. The through-hole penetrates in a third positive direction. A first coil extends inside the multilayer body while surrounding an outer circumference of the through-hole. A magnetic resin is filled into the through-hole. An overlying adhesive resin layer is laminated on a first surface of the multilayer body. An upper magnetic substrate is adhered to the multilayer body with the overlying adhesive resin layer interposed therebetween. The overlying adhesive resin layer includes an accommodation space. The accommodation space is connected to the through-hole. When the multilayer coil component is seen in the third positive direction, an outer edge of the accommodation space is located on an outer side of an outer edge of the through-hole. A portion of the magnetic resin is located inside the accommodation space.

Abstract: An inductor component comprising an element body having laminated insulating layers; a coil in the element body and wound into a helical shape advancing in a lamination direction of the insulating layers; and a substrate on an upper surface of the element body. The coil includes coil wirings along the lamination direction and wound along a plane orthogonal to the lamination direction, and a connection wiring connecting end portions of the coil wirings. The coil wirings include a winding part wound on the plane and a lead-out part from an end portion of the winding part to the connection wiring which is one of connection wirings arranged in the lamination direction. In the lamination direction, a lowest position of an upper surface of the connection wiring of the uppermost layer is lower than a bottom surface of the winding part in the coil wiring of the uppermost layer.

Abstract: A thin inductor component includes an element body having a principal surface and a side surface perpendicular to the principal surface. An inductor wire extends in parallel with the principal surface. From the inductor wire, a first vertical wire extends in a direction toward the principal surface, and a first support wire extends in parallel with the principal surface. The first vertical wire and the first support wire are connected to a first pad of the inductor wire. When a virtual tangent is drawn at a connection point of the inductor wire main body to the first pad with respect to the center axis of the wire main body when viewed from the thickness direction, the first support wire extends from the first pad in parallel with the virtual tangent and the center axis of the first support wire and the virtual tangent are located on different straight lines.
