Abstract
A method of making a laminated film capacitor comprising a plurality of dielectric layers and a corresponding number of film electrodes which are alternately laminated one above the other with peripheral edges of both of the dielectric layers and film electrodes being exposed to the outside of the capacitor through a peripheral cut side face defined in such capacitor. Each of the dielectric layers is made of material having a lower UV laser beam absorptivity than that of material for each of the film electrodes. A UV laser beam is radiated to the peripheral cut side face to preferentially remove the peripheral edges of the film electrodes which are situated adjacent to the peripheral cut side face of the capacitor.
