<p><P>PROBLEM TO BE SOLVED: To improve the durability of a release layer of a welding tool having the release layer composed of a fluorocarbon compound. <P>SOLUTION: The tool 20 for hot-plate welding includes: a metal layer 10 formed so as to come into contact with a part to be hot-plate welded of a resin component; a nitride ceramic thin film 12 having wear resistance which is laminated on the metal layer; and the release layer 16 formed of a thin film of the fluorocarbon compound laminated on the nitride ceramic thin film. An active layer 14 is formed between the nitride ceramic thin film 12 and the release layer 16. In the active layer, a reactive group of the nitride ceramic and a reactive group of the fluorocarbon compound are bonded by activating treatment. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
