摘要： A solid electrolytic capacitor includes a capacitor element including an anode part and a cathode part, an anode lead frame electrically connected to the anode part, a cathode lead frame electrically connected to the cathode part, and an exterior body covering the capacitor element. The anode lead frame includes a first buried part that is a part of the anode lead frame and is buried in the exterior body, and the cathode lead frame includes a second buried part that is a part of the cathode lead frame and is buried in the exterior body. A plurality of recesses are formed on a surface of at least one of the first buried part or the second buried part.

摘要： 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.

摘要： A solid electrolytic capacitor includes a capacitor element, an anode lead frame, a cathode lead frame, and an exterior body. The anode lead frame includes a first buried part that is a part of the anode lead frame and is buried in the exterior body. The cathode lead frame includes a second buried part that is a part of the cathode lead frame and is buried in the exterior body. A plurality of recesses are formed on a surface of at least one of the first buried part or the second buried part. The plurality of recesses include a plurality of first recesses formed on a surface of the first buried part. The solid electrolytic capacitor further includes an insulating film disposed to cover at least one selected from the group consisting of at least a part of the anode part and at least one of the plurality of first recesses.
