Abstract
A solid electrolytic capacitor element includes an anode body including a porous part, a dielectric layer, and a cathode part. The cathode part includes a solid electrolyte layer covering the dielectric layer. The anode body includes a first anode body part on which the solid electrolyte layer is disposed and a second anode body part on which the solid electrolyte layer is not disposed. The solid electrolyte layer includes a first solid electrolyte layer disposed in the porous part and a second solid electrolyte layer disposed outside the porous part. When a length of the first anode body part in a longitudinal direction thereof is defined as a length L, a thickness of the second solid electrolyte layer in a first region is more than or equal to 1 μm. The first region is a region between boundary between the first anode body part and the second anode body part and a position located away from boundary in a lengthL in the first anode body part.
