Abstract

An anode body, a dielectric layer disposed on a surface of the anode body, and a cathode part covering at least a part of the dielectric layer are provided. The cathode part includes a solid electrolyte layer covering the at least the part of the dielectric layer and containing a conjugated polymer. A solid electrolytic capacitor having excellent heat resistance is provided by using a solid electrolytic capacitor element where a full width at half maximum of a first peak is in a range from 35 cmto 80 cminclusive when the first peak attributed to a CC stretching vibration derived from the conjugated polymer is fitted with a Lorentz function in a Raman spectrum of the solid electrolyte layer.
