PURPOSE:To inhibit the deterioration of a metallized organic film in an insulating groove section formed when the insulating groove section is shaped at one part of the organic film by applying a laser beam by bringing a coolant transparent to laser beam into contact with the point to be irradiated with the laser beam. CONSTITUTION:A metallized organic film 3 is irradiated with laser beams L, insulating groove sections 8 are shaped to one parts of the film 3, and the metallized organic film 3 is wound or a plurality of the films 3 are laminated, thus manufacturing a metallized organic film capacitor. A coolant 7 transparent to laser beans L is brought into contact with a point 3a to be irradiated with laser beams L in the metallized organic film 3 in the forming process of said insulating groove sections 8 in such a case. The long-sized single-sided metallized organic film 3 wound in a roll shape is delivered in succession, the round bar- shaped coolant 7 such as sapphire transparent to laser beams L is disposed on the rear side of a metallized organic film section 3a irradiated with a laser- beam irradiating means 6 under the state of contacts with the film 3, and the insulating groove sections 8 are shaped. |
