PURPOSE:To sharply reduce manufacturing cost and to improve heat shock resistance and withstand voltage by interposing a dielectric between a through terminal and an external electrode terminal surrounding it thereby forming capacitance. CONSTITUTION:A through capacitor 30 comprises cylindrical electrodes 33 and 34, where two through terminals 31 and 32 pierce the axial positions, complex dielectrics 35 which are filled in those, a grounding terminal plate 36, and insulating electrode cases 37 and 38. The cylindrical electrodes 33 and 34 consist of cylindrical pipes and are fixed to the grounding terminal plate 36, conductivity. Complex dielectrics 35 are filled in the cylindrical electrodes 33 and 34 after insertion of the through terminals 31 and 32, and are hardened. The complex dielectric 35 is one where ceramic powder such as BaTiO3, SrTiO3, or the like is mixed in epoxy resin as the base. |
