A method for manufacturing a solid electrolyte capacitor, the method including: preparing a connection body including a frame and a plurality of capacitor elements, the frame including a plurality of element connection units and a coupling portion that integrally couples the plurality of element connection units with each other, the plurality of element connection units being provided along a first direction and a second direction intersecting with first direction the plurality of capacitor elements being connected to the plurality of element connection units; sealing the plurality of capacitor elements by using a sealing resin having a stripe shape that extends in the first direction; forming a groove in the sealing resin by running a blade along the second direction between the capacitor elements adjacent in the first direction; and segmenting the plurality of capacitor elements by cutting the sealing resin along a bottom surface of the groove by laser and cutting a boundary between each of the plurality of element connection units and the coupling portion by laser.

Solid electrolyte capacitor and method for manufacturing same

A solid electrolytic capacitor includes a capacitor element. The capacitor element includes an anode body that is a porous sintered body, a dielectric layer disposed on a surface of the porous sintered body, an insulating material disposed on a surface of the dielectric layer, and a solid electrolyte layer disposed on a surface of the insulating material. The capacitor element has at least one corner part. An amount of the insulating material disposed in the at least one corner part of the capacitor element is larger than an amount of the insulating material disposed in a center part of the capacitor element.

Solid electrolytic capacitor

A solid electrolytic capacitor includes a capacitor element including an anode portion and a cathode portion, an anode terminal electrically connected to the anode portion. The anode portion includes an anode body and an anode lead extending from the anode body. The anode terminal includes a first main surface and a second main surface opposite to the first main surface. The anode terminal includes a middle section, a first extension section and a second extension section, the first extension section and the second extension section being respectively disposed at both sides of the middle section. The first extension section has a first end part and is bent so that a tip of the first end part faces the second main surface. The second extension section has a second end part and is bent so that a tip of the second end part faces the second main surface. The anode lead connects with the first main surface of the anode terminal at the first end part and at the second end part.
