PROBLEM TO BE SOLVED: To strike a balance between the improvement of moisture resistance and the stabilization of a self-recovering function, concerning a metalized film capacitor which is used in an automobile field or the like. SOLUTION: The metalized film capacitor is structured by using a metalized film, which is formed by arranging an insulation margin 3 continuously in a longitudinal direction on one end side of a width direction of a dielectric film 1, forming a metal vapor deposition electrode 2 on a part except for the insulation margin 3, and forming a protective film 5 formed of a silicon oxide film or silicon dioxide film containing 2-50 vol.% of hydrogen on the metal vapor deposition electrode 2. Thereby, a flexible and precise film is formed to exhibit a better coating property than a protective film formed of organic oil. Thus, the moisture resistance and corrosion resistance are improved. Furthermore, the film provides corrosion resistance improving effect even with a thinner film than a protective film formed of inorganic metal oxide to prevent the degradation of the self-recovering function. Accordingly, the moisture resistance and corrosion resistance are improved, and at the same time, the self-recovering function and ease of operation of a self safety mechanism can be stabilized.
