<P>PROBLEM TO BE SOLVED: To provide a resin composition for laser welding which can be suitably used particularly when a polyolefin resin material is used as a resin material, in a method for joining an inorganic material such as a metal material, a glass material, a ceramic material, or a composite thereof with the resin material, wherein the method can form a firm joining part by a simple procedure without limiting the application field, and to provide a formed article using the resin composition. <P>SOLUTION: The resin composition for laser welding for making a formed article for directly welding an inorganic material selected from a metal, a ceramic, a glass, and a composite thereof with a resin by laser welding comprises a polyolefin resin containing a polar group. Further, in the formed article for laser welding for directly welding an inorganic material selected from a metal, a ceramic, a glass, and a composite thereof with a resin by laser welding, a layer containing a polyolefin resin containing a polar group is present at the welding interface of the inorganic material and the resin. <P>COPYRIGHT: (C)2008,JPO&INPIT |
