Abstract: A multi-layered solid electrolytic capacitor including capacitor elements, each comprising an anode body having an anode portion and a cathode portion having a dielectric oxide film and a cathode layer formed in succession on a surface of the anode body, the capacitor elements being stacked on top of one another and the anode portions being weld-secured to anode mounting surfaces of anode mounting parts provided in an anode terminal. The multi-layered solid electrolytic in which the anode mounting parts are provided such that the anode mounting parts are disposed parallel to each other, and adjacent anode mounting parts are joined to each other by a joint part.

Abstract: [Problem] Mechanical stress in welding is suppressed, a tilt of the elements is suppressed in relation to the increase in the number of layers so that LC defects are alleviated, whereby an increase in capacitance due to a greater number of layers is achieved. [Means for Solving the Problem] In a solid electrolytic capacitor, capacitor elements (30) are disposed in a stacked state and anode portions (30a) are weld-secured to anode mounting surfaces of anode mounting parts (7a), (7b) provided for an anode terminal. Two anode mounting parts (7a), (7b) are provided, and the anode mounting parts are disposed parallel to each other, and adjacent anode mounting parts (7a), (7b) are joined to each other by a joint part (9).

Abstract: A multi-layered solid electrolytic capacitor is furnished with a plurality of capacitor elements 6, each having an aluminum foil 1 having an anode portion 7 and a cathode portion 8 having a dielectric oxide film 2 and a cathode layer 3 successively formed on a surface of the aluminum foil 1. The capacitor elements 6 are stacked on each other. Adjacent anode portions 7 of the capacitor elements 6 are welded to one another and adjacent cathode portions 8 are electrically connected one another by a conductive paste layer 18. An insulative resin layer 16 is disposed on a boundary between the cathode portion 8 and the anode portion 7 of at least one of the capacitor elements 6 and on an adjacent region thereto.

Abstract: A solid electrolytic capacitor including a capacitor element having an anode body partly provided with a cathode layer, an anode-side and a cathode-side lead frame attached to a lower surface of the capacitor element, and a housing covering the lead frames and the capacitor element except lower surfaces of the lead frames. Both of the lead frames are exposed on the bottom face of the housing. The anode-side lead frame extending longitudinally of the capacitor is provided in an outer end portion thereof with at least two strips which separate each other. Outer end portions of the strips are exposed on the outer end face of the housing. A concave space is formed between the strips and is filled with resin forming the housing.
