Solid electrolytic capacitor and method for manufacturing same

This solid electrolytic capacitor includes at least one solid electrolytic capacitor element including a sheet-shaped anode body having a porous portion in a surface layer, a dielectric layer covering at least a portion of the porous portion, and a cathode portion covering at least a portion of the dielectric layer. The cathode portion includes a solid electrolyte layer covering at least a portion of the dielectric layer. The solid electrolyte layer includes a first layer that covers at least a portion of the dielectric layer and includes a first conductive polymer, and a second layer that covers at least a portion of the first layer and includes a second conductive polymer. The first layer has an inner layer filled in the voids of the porous portion having the dielectric layer, and an outer layer exposed from the main surface of the porous portion having the dielectric layer. By using a solid electrolytic capacitor in which the thickness (Tm) of the outer layer exposed from the main surface is 1 [mu] m or mo
