Claim 7:
8. A method for manufacturing a solid electrolytic capacitor, the method comprising:
(i) forming a dielectric layer on at least a part of a surface of an anode foil, the anode foil including a base material part and a porous part disposed on a surface of the base material part;
(ii) conducting at least one of compression or removal of, after defining an anode section, a cathode formation section, and a separation section between the anode section and the cathode formation section in the anode foil on which the dielectric layer is formed, at least a part of the porous part in the separation section;
(iii) disposing a first insulating material in at least a part of the separation section or impregnating the at least a part of the separation section with the first insulating material;
(iv) covering at least a part of the dielectric layer in the cathode formation section with a solid electrolyte layer;
(v) covering at least a part of the solid electrolyte layer with a cathode lead-out layer; and
(vi) after step (v), disposing a second insulating material in at least a part of a region of the separation section or impregnating the at least a part of the region of the separation section with the second insulating material, the region of the separation section being located closer to the anode section than the first insulating material, wherein:
the method further comprising after step (ii) and before step (iv), forming a first groove by removing at least a part of the porous part in a region of the separation section, the region of the separation section being located closer to the anode section than the first insulating material, and
in the step (vi), the second insulating material is disposed in at least a part of the first groove.
