Abstract: An electrolytic capacitor includes at least one capacitor element including: an anode body including a porous part in a surface layer; a dielectric layer covering at least a part of a surface of the anode body; and a solid electrolyte layer covering at least a part of the dielectric layer. The solid electrolyte layer includes, in the anode body, a first portion disposed in a void of the porous part, and a second portion disposed outside a principal surface of the anode body. The second portion includes n or more conductive polymer layers on one principal surface of the anode body. Following relational expressions are satisfied: 18. μm ≤ T t ≤ 50. μm 9. μm ≤ Tt / n ≤ 12.5 μm where, n is an integer of 2 or more, and Tt is a thickness of the second portion on one principal surface of the anode body having the dielectric layer.
