Abstract: A solid electrolytic capacitor element includes an anode foil having a porous part at a surface layer, a first portion including a first end and a second portion including a second end opposite the first end, a dielectric layer formed on the surface of the porous part, and a solid electrolyte layer covering at least a portion of the dielectric layer. The solid electrolytic capacitor element has an insulating region containing a cured product of a resin composition between the first and second end of the anode foil. In the insulating region, pores of the porous part are filled with the cured product. The resin composition contains an insulating resin material and an additive that modifies the insulating resin material. The content rate of the additive in the resin composition is 3% by mass or more. The glass transition point of the cured product is 230° C. or more.

Abstract: A solid electrolytic capacitor includes a capacitor element. The capacitor element includes an anode foil including a base material part and a porous part disposed on a surface of the base material part, a dielectric layer disposed on at least a part of a surface of the anode foil, a solid electrolyte layer covering at least a part of the dielectric layer, and a cathode lead-out layer covering at least a part of the solid electrolyte layer. The anode foil includes an anode section on which the solid electrolyte layer is not disposed, a cathode formation section on which the solid electrolyte layer is disposed, and a separation section located between the anode section and the cathode formation section. A first insulating material is disposed on a surface of the porous part in the separation section. And at least a part of a region of the porous part that is covered with the first insulating material includes a second insulating material.
