PROBLEM TO BE SOLVED: To provide a pipe joint heater component easily mountable on a joint while stabilizing its assembling quality, and post-mountable on an existing joint while reducing cost such as molding cost burden. SOLUTION: The pipe joint heater component 1 which holds a heater wire H inside and has an inner face shape to be fitted to the outline of the joint is fitted and mounted onto the joint 10 through the outside, where the heater wire H is energized to conduct the heat of the heater wire H to the joint 10. Preferably, it has a partial fitting portion 2 of the inner face shape to be fitted to part of the outline of the joint and a holding recessed portion 3 formed in the other inner face than the fitting portion for holding the heater wire. The heater wire H held by the holding recessed portion 3 abuts on the joint 10. COPYRIGHT: (C)2009,JPO&INPIT
