PURPOSE:To thermal-weld a conductive rubber-plastic layer to a rubber plastic molded product by heating only the conductive rubber-plastic layer, while keeping the rubber-plastic molded product at unheated state. CONSTITUTION:When the magnetic field from a high frequency magnetic field generator 3 is radiated on a conductive rubber-plastic layer 2, the voltage, as a magnetic field generating source acting so as to deny said magnetic field as its reaction, is generated. The generation of such voltage is limited to conductive material, and it is not generated in the dielectric such as rubber-plastic molded product. If the conductivity of the rubber-plastic layer is equal to 10<5>OMEGA.cm or less (e.g. 10<-3>OMEGA.cm-10<5>OMEGA.cm), the voltage, as a reaction, is generated only in the rubber-plastic layer 2. The conductive rubber-plastic layer 2 is only heated by electrically generated heat due to said voltage, thereby thermal welding the conductive rubber-plastic layer 2 to a rubber-plastic molded product 1. |
