PROBLEM TO BE SOLVED: To improve vibration resistance of an electronic component and to improve heat dissipation of the electronic component. A magnetic body (4) having a hollow portion, a conductor (6) penetrating the hollow portion of the magnetic body (4) and protruding from the hollow portion, a dielectric layer (30) formed on the surface of the conductor (6), and a dielectric layer. The solid electrolyte layer 32-2 formed on the surface of 30, the extraction layer electrically connected to the solid electrolyte layer 32-2, the magnetic body 4 and the conductor 6, and the magnetic body. 4 and a resin 8 that contacts the conductor 6.
