<p>PURPOSE:To selectively remove the metallic thin film by irradiating the laser beam on the metallized film running while being wound on the rotating metallic drum. CONSTITUTION:The metallic thin film is removed selectively by winding the metallized film 7a whose thin film surface is made to the outer side on the circular column like metallic drum 1 having the roughness <=0.4S of the front surface and being rotationable, and irradiating the laser beam 8 while running to the metallized film 7a running on the drum. Therefore, for example, the metallized film of the thickness <=1.2mum being set the non-metallic belt of extra fine width <=0.2mm width which is required for manufacturing the extra small size film capacitor can be easily manufactured.</p> |
