摘要：
A film capacitor includes a body including a core body formed of an insulating material and metalized films which are wound around the core body; and first and second terminal electrodes disposed on both end surfaces in an axial direction of the body, respectively, a cross section perpendicular to an axial direction, i.e., z direction, of the core body having an oval outer periphery having a major axis and a minor axis, and an inner periphery defining a slit extending along the major axis. The provision of the core body makes it possible to suppress loosening of the metalized films or occurrence of a gap between the metalized films, thus making the film capacitor having a high insulation property.
