Bonding Method And Hot-Melt Adhesive Film For Induction Heating

A bonding method for bonding a first adherend made of a first resin and a second adherend made of a second resin different from the first resin together, the method comprising:

• stacking the first adherend, a hot-melt adhesive film for induction heating, and the second adherend in this order, to obtain a stack;
• and
• heating the hot-melt adhesive film for induction heating using an induction heating device,
• wherein the hot-melt adhesive film for induction heating is a hot-melt adhesive film for induction heating in which a thermoplastic resin layer (A′) composed of a thermoplastic resin (A), a metal layer, and a thermoplastic resin layer (B′) composed of a thermoplastic resin (B) are laminated in this order, and
• in the stack, the first adherend and the thermoplastic resin layer (A′) are in contact with each other, and the second adherend and the thermoplastic resin layer (B′) are in contact with each other.
