Claims (1)

[Scope of Claim for Utility Model Registration] (1) A pipe-shaped pipe having openings at both ends and having a coating of insulating material from the opening end to a predetermined portion of the outer surface, except for one end that becomes the cathode terminal. A capacitor comprising a metal case, a cathode conductive layer electrically and mechanically connected to the inner wall surface of the metal case by soldering, and an anode lead wire protruding from the opening of the metal case without contacting the metal case. an electrically and mechanically connected portion of the anode lead-out wire of the capacitor element protruding from the metal case opening by welding, and located substantially on the same plane as the metal case as a cathode terminal, and the protruding lead-in wire; A chip-shaped solid electrolytic capacitor consisting of a plate-shaped solderable anode terminal and a plate-shaped solderable anode terminal having a cut groove into which the capacitor is fitted. (2) The chip-shaped solid electrolytic capacitor according to claim 1 of the utility model registration, which is reinforced by applying resin to the base of the anode lead wire of the capacitor element. (3) The chip-shaped solid electrolytic capacitor according to claim 1 of the Utility Model registration claim, which is formed by filling an insulating material at the open end of a metal case and between the metal case and the anode terminal. (4) The chip-shaped solid electrolytic capacitor according to claim 1, which is a utility model registration, wherein an anode terminal is brought into contact with the open end surface of a metal case through a film made of an insulating material. (5) The chip-shaped solid electrolytic capacitor according to claim 1, in which the anode terminal is formed by providing a notch in the tip of a comb-shaped metal frame and bending the anode terminal at the notch. (6) The chip-shaped solid electrolytic capacitor according to claim 5, which is a utility model, and has a notch in the tip of the separation piece of the metal frame so that the tip is separated into three pieces.
