PROBLEM TO BE SOLVED: To enhance moisture resistance of a metallization film capacitor for use in a hybrid automobile, or the like. SOLUTION: In the metallization film capacitor 1 where metallicon electrodes 3 are formed on the opposite end faces of an element 2 formed by winding a pair of metallization films each having a metal deposition electrode formed on a dielectric film such that the metal deposition electrodes oppose through the dielectric film, metallization films 4 and 5 having metal deposition electrodes 4b and 5b of lower resistance than that of the metal deposition electrodes constituting the element 2 formed on one side of polypropylene dielectric films 4a and 5a thicker than the dielectric film constituting the element 2 are wound around the outer circumference of the element 2. Consequently, moisture resistance is enhanced sharply, capacitance as the metallization film capacitor 1 is expanded because the metallization films 4 and 5 wound around the outer circumference of the element 2 bear a part of capacitance, the size is not enlarged unnecessarily and small size large capacity is not affected.
