ABSTRACT:
Capacitor elements having an ultra thin dielectric layer are made by the method of cutting a metal-deposited polyethylene terephthalate laminated film into a predetermined width, and then separating a metal-deposited polyethylene terephthalate film from the cut laminated film and successively forming the separated metal-deposited polyethylene terephthalate film into a coil. The metal-deposited polyethylene terephthalate laminated film is composed of an oriented ultra thin polyethylene terephthalate film having a thickness of 0.2 to 2.0 .mu.m, on one surface of which a metal layer is formed by vacuum deposition and on the other surface of which a propylene copolymer support film is bonded with an adhesive force of 0.1 to 2.0 g/cm.
