Abstract
A film capacitor includes a main body portion and external electrodes. The main body portion includes a dielectric film and a metal film that is disposed on one surface of the dielectric film. The metal film has surface roughnesses of Sand Swhere Sdenotes a surface roughness of the metal film in a first direction, and Sdenotes a surface roughness of the metal film in a second direction. The first direction is perpendicular to the second direction. Sis greater than S. The main body portion includes a pair of ends in the first direction thereof. The external electrodes are disposed on the pair of ends in the first direction of the main body portion, respectively. An average value of fractal dimensions of irregularity boundary lines due to wrinkles of the metal film is 1.08 or more.
