PROBLEM TO BE SOLVED: To make it possible to apply a heater to the whole surface of a conducting piece definitely when bonding fixedly a waterproof sheet with a waterproof substrate by way of a thermal deposition material layer by electromagnetic induction heating. SOLUTION: When a waterproof sheet 2 is placed in contact with a contact surface between an electromagnetic induction heater 6 and the waterproof sheet 2, there is provided a guide 8 which surrounds a conducting piece 3 and prevents the contact surface from coming out of the conducting piece 3. When the sheet 2 is constructed with the heater 6, at first the conducting piece 3 is provided at a specified position of a waterproof substrate 1 where the conducting piece 3 has a thermal deposition material layer 5. The waterproof sheet 2, which covers the whole surface of the substrate, is put up all over the whole surface of the substrate 1. Then, the conducting piece 3 is heated with the heater 6 from the waterproof sheet 2 so that the waterproof sheet 2 may be joined with the conducting piece 3 by means of the molten thermal deposition material layer. During this heating time, the heater 6 can be applied smoothly all over the whole area of the conducting piece with the guide 8. |
