1. A film capacitor comprising:
a capacitor element including one or more wound or laminated metallized films, each metallized film including a resin film and a metal layer on a surface of the resin film;
an outer case that houses the capacitor element, wherein the outer case is made of a resin composition containing a liquid crystal polymer and 5 wt % to 60 wt % of an inorganic filler, and has a bending strength of 120 MPa to 250 MPa; and
a filling resin that fills a space between the capacitor element and the outer case.
