<p><P>PROBLEM TO BE SOLVED: To provide a laser cutting method that facilitates obtaining of laser energy for laser cutting and that dispenses with special surface treatment of a material to be cut in a pre-cutting stage. <P>SOLUTION: Before laser cutting of a material B to be cut, a film 17a capable of absorbing laser energy is formed on the surface of the material B in the area including an intended cutting line 23 and its proximity. Thereafter, laser cutting is performed along the cutting line 23 where the film 17a is formed. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
