Abstract: An electronic component includes a main body made of an insulator, a circuit element positioned inside the main body, and outer electrodes. The outer electrodes are constituted of bottom surface electrodes and post-like electrodes. The post-like electrodes are extended from a bottom surface of the main body toward the interior of the main body. Further, the post-like electrodes are embedded in the main body, and parts of the post-like electrodes are exposed to side surfaces of the main body. Furthermore, the bottom surface electrodes are made of a resin containing metal powder.

Abstract: An insulating layer, which is composed of a material having a higher insulating property than a core, partially covers a surface of the core. A plating layer, which functions as an electrode, is stacked on a surface of the insulating layer. The surface area of the insulating layer is larger than the surface area of the plating layer and the plating layer is stacked inside a region covered by the insulating layer.
