PURPOSE:To enhance the design effect of a product after the bonding of a plastic part and to obtain the sufficient bonding strength of a welded bonded part in an induction heating weld sheet used in the bonding of the plastic part. CONSTITUTION:A resin layer 6 containing no inductive element is laminated to a welding resin layer 4 wherein inductive elements 2 are added to a thermoplastic resin sheet matrix 1 to form a two-layered structure. The material quality of the welding resin layer 4 is made same to that of one plastic part and the material quality of the resin layer 6 for a composite layer is made same to that of other plastic part. Further, if necessary, the resin layer 6 is properly colored. |
