<P>PROBLEM TO BE SOLVED: To form a structure in which, as a film capacitor, reliability, specially humidity resistance can be maintained by forming the structure in which a filling resin is easy to be sealed. <P>SOLUTION: A film capacitor includes: a capacitor element using a film for a dielectric body; a bottomed cylindrical metal case having an opening on the upper end surface, in which this capacitor element is housed; a resin cap which seals the opening of this metal case; and a filling resin with which the inside of the metal case is filled. Along the side surface directions of the metal case, cylindrical overhang parts are provided which overhang integrally from a peripheral part of the resin cap, these overhang parts are provided with fitting portions to be fitted into the opening of the metal case. In these fitting portions or on one of opposing surfaces in the vicinity of the opening of the metal case in contact with these fitting portions, protrusions are provided which push and expand gaps between the fitting portions and the vicinity of the opening of the metal case. <P>COPYRIGHT: (C)2013,JPO&INPIT |
