Original Abstract Submitted

A capacitor element includes an anode body including a first portion including a first end and a second portion including a second end, and a separation part disposed on a part positioned between the first end and the second end of the anode body. The conductive polymer layer includes an inner layer filled in at least a part of the porous part, and an outer layer positioned outside a principal surface of the anode body. The separation part includes an end A and an end B, the end B being positioned closer to the second end than the end A is. A filling proportion in a region C included in a cross section of a portion of the porous part from the end B to 0.05L is more than or equal to 46%, where L represents a length from the end B to an end of the cathode part at the second end side.
