<P>PROBLEM TO BE SOLVED: To perform high quality adhesion for polymeric films such as polyvinyl alcohol resin films while reducing use of light absorbent. <P>SOLUTION: There is provided an adhesion method of a polymeric film in which a surface of a polymeric film is brought into contact with a surface of an opposite material and their boundary surface is laser-welded. The adhesion method of the polymeric film is characterized in that a laser beam is irradiated while at least the boundary surface side of the polymeric film is in an absorption of water state, and the laser welding is performed by absorbing the laser beam by the absorbed water. <P>COPYRIGHT: (C)2012,JPO&INPIT |
