ABSTRACT:
A chip type tantalum capacitor has an insulating resin frame, a pair of substantially flat metal foil terminals bonded to both sides of the frame, at least one of the frame sides having a slit therethrough and open to the outside of the metal foil terminal on the one frame side, the metal foil terminal on the one frame side being a metal selected from the group consisting of copper and nickel. A tantalum capacitor element having a pair of terminals is enclosed in the frame, at least one of the element terminals being a lead wire made of tantalum, the lead wire extending through the slit and outside the metal foil terminal on the one side of the frame and being bent at the outside surface of the metal foil terminal with the bent portion of the lead wire outside the metal foil terminal extending along the surface of the metal foil terminal and being welded to the metal foil terminal surface for being fixed thereto, the other element terminal being electrically connected to the other metal foil terminal. An insulating resin is potted in the space inside the frame and around the capacitor element.
