PROBLEM TO BE SOLVED: To increase the electrical connection area of internal and external electrodes and to increase an allowable pulse current by laminating or winding a dielectric film that has shrunk in a width direction due to heating so that a double-sided metallized film projects toward both sides in the width direction by a specific length after slitting into a specific slit width. SOLUTION: A double-sided metallized film 1 that is slit into a specific width while an electrode is formed on both the surfaces of a wide dielectric film 2 in a stripe shape in the longitudinal direction by deposition, and the wide dielectric film 2 are slit into±0.2 mm of the slit width of the double-sided metallized film. After that, the dielectric film that has shrunk in a width direction due to heating is laminated or wound so that the double-sided metallized film projects by 0.03 mm or more and 0.4 mm or less at both sides in the width direction of the dielectric film. Also, shrinkage by the heat of the dielectric film due to heating after slitting is within a range of 0.2% or more and 10% or less for the slit width for obtaining stable shrinkage, thus controlling shrinkage dimensions.
