PURPOSE: A method for fabricating a condenser core is provided to prevent the formation of wrinkles of a thin film and at the same time to prevent the damage of the thin film due to the stress, and accordingly to improve the performance of a condenser. CONSTITUTION: In the formation of a film condenser used as an electrode by a metal film suck as an aluminum or a zinc between a plurality of dielectric layers of ultra thin plastic films, a condenser core(40) is provided which is used in winding a plastic film including a metal film. The condenser core is formed in a tube shape, and the shape of a cross section of the external wall of the condenser core is fabricated in a cylindrical shape, and the cross section of the internal wall is fabricated in a shape having an eccentric part from the center of a rotation axis to receive a rotation force. The thickness of the inner wall and the external wall are formed uniformly along a lengthy direction with a material having the endurance and heat resistant property. |
