And a method for fusing a polyolefin resin adherend by scissoring a fusion material obtained by kneading a carbon black with a polyolefin resin and applying a high frequency to the fusion material scissors portion, and JP-B-5-11022. As disclosed in Japanese Patent Laid-Open No. 3-186690 and Japanese Patent Laid-Open No. 3-186690, a heat generating material made of a vinyl chloride resin, a polyamide resin, an ethylene-vinyl acetate copolymer, a polyester resin, a phenol resin or the like having a large dielectric loss value is used. There is a method of interposing it on the fusion interface and fusing. Further, as disclosed in JP-A-5-504153, by irradiating a conductive polymer such as polyaniline with microwaves, the conductive polymer is dielectrically heated to fuse the resin. There are ways.

There are problems such as deterioration of the resin and difficulty in controlling the heat generation temperature. Further, when a resin having a large dielectric loss is used, there is a problem that it takes a long time to raise the temperature.
Further, when polyaniline is used, there are problems that the polyaniline is self-deteriorated by its own heat generation and that the peel strength of the fusion-bonded surface is lowered due to the presence of polyaniline.

However, the above method is bulky and requires a plurality of pairs of heating tools for each tube size, which requires time for joining, which is troublesome.
