MANUFACTURE OF FILM CAPACITOR

摘要

PURPOSE:To realize reliable and effective manufacture by eliminating a section of a dielectric on the side of an electrode drawing edge face in preference to an electrode to expose an electrode to the edge face and simultaneously by forming an irregular edge face between dielectric layers. CONSTITUTION:A proper laser beam 2 having a wave length of at least about 0.4mum is irradiated to an end of an electrode drawing side of a film capacitor 3 whose adsorption rate against a laser beam having a wavelength of 0.4mum or below is higher in a dielectric material than in an electrode material to eliminate a dielectric section in preference to an electrode 5. The electrode 5 is exposed to an edge face and irregularity is formed between layers of lami nated dielectric 4. Since an edge face of each dielectric of an electrode drawing end side is made irregular, an edge face electrode 7 formed thereto keeps good electric contact with an electrode and attaches firmly thereto. Reliability can be thereby acquired and effective manufacture is realized.
