Claim 0:
1. A solid electrolytic capacitor comprising:
a capacitor element including:
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, wherein:

the anode foil includes an anode section, a cathode formation section, and a separation section located between the anode section and the cathode formation section, the cathode formation section being covered with the solid electrolyte layer, the anode section being not covered with the solid electrolyte layer and other than the separation section,
a first insulating material is disposed on a surface of the porous part in the separation section,
the porous part of the separation section has a first region, a second region, and a third region, the first region being located between the first insulating material and the base material part, the second region being located closer to the cathode formation section than the first insulating material, the third region being located closer to the anode section than the first insulating material,
voids of the porous part in at least a part of the first region are filled with a second insulating material, and
voids of the porous part in at least a part of the third region are filled with the second insulating material.
