PROBLEM TO BE SOLVED: To obtain an excellent capacitor excellent in the impregnation property with insulating layer, reduced in the lowering of insulating capacity caused by long-term charge under a high temp. and high voltage condition and keeping tanδ,ΔC characteristics by using a metallized film. SOLUTION: This metallized film is obtained by vapor-depositing a metal on at least the single surface of a biaxially stretched polypropylene film. In this case, this biaxially stretched polypropylene film contains 0.02-0.1 pts.wt. of an epoxy compd. and the m.p. peaks thereof by a scanning type differential calorimeter are two or more. |
