Abstract
An electrolytic capacitor includes an anode body, a dielectric layer covering at least a part of the anode body, and a solid electrolyte layer covering at least a part of the dielectric layer. The anode body is a sintered body of valve metal particles. A total number of defects of the dielectric layer to be found is less than or equal to four in a condition that six regions are arbitrarily set in a surface of the anode body, and each of the six regions is observed in a visual field of 100 μm2.
