ABSTRACT:
When resin members (3, 4) are fusion-bonded to each other by electric-conduction heating, a net-form or pattern-form metal wire (2) as a resistance heating element is disposed at a joint portion of the resin members (3, 4), and a metal wire (2) is heated by electric conduction for fusion-bonding the abutting resin members (3, 4) at temperatures sufficient for fusion-bonding with the resin members kept abutting against each other. A production method for a resin-processed product that can increase the strength of the joint portions between resin members, is free from carbon generation and short-circuiting during the electric conduction of a built-in resistance heating element (heating element), and is simple to produce while hardly being affected by environmental temperatures.
