PROBLEM TO BE SOLVED: To provide a safe and highly reliable dry type high voltage film capacitor even when a plurality of capacitor elements are serially connected and used with a high voltage. SOLUTION: A continuous conductive path 6 is formed on the side edge metallic evaporation face of a metallized film 1 in which an evaporation metallic electrode 3 is formed while an insulating margin part 2 is left at one edge part of the width direction of the film. The evaporation metallic electrode 3 is divided by a dividing groove 7 extended to the width direction or obliquely from the width direction so that a plurality of split electrodes 8 can be formed. The top end of the dividing groove 7 which is intermittently extended to the longitudinal direction is allowed to cross a semi-circular or semi-elliptic insulating groove 9a like a T shape, and at least another insulating groove 9b is formed through a connecting part 10 between the insulating grooves 9a. At least one metallized film 1 is wound around a capacitor elements 5, and those capacitor elements 5 formed by spraying metal to both the edge faces of this wound body, and forming electrode leading parts 11 are connected serially or in serial/parallel in this dry type high voltage metallized film capacitor. The width direction 11 of the connecting part 10 is set 1.0-5.0 mm, and the width direction 12 of the insulating grooves 9a and 9b is set 1.0-10.0 mm.
