る。As described above, conventionally, the film adhesive 3 is sandwiched between the bonding surfaces of the bonding members 1 and 2, and the two members are heated and bonded under a surface pressure. . By this heating, the film adhesive 3 melts and gels, and the gelled adhesive spreads on the bonding surface and then hardens to complete the bonding. At this time, the excess gel-like adhesive protrudes from the end face of the bonding portion and hardens as schematically shown in FIG.

用がかかることになる。[0005] In the case of parts that generally require precision, such as jet engine parts, the adhesive that has protruded from the end face of the bonded part and has hardened must be removed. However, the cured adhesive is firmly adhered also to the parts protruding from its properties, and is very difficult to peel off, and it takes time to remove it. In addition, when cutting is used for removing the adhesive, if one of the adhesive members is softer than the hardened adhesive (for example, Teflon), the adhesive member may be bitten by a tool blade and may be scratched. Further, if the parts are mounted on a predetermined processing device (lathe, NC milling machine) or the like to prevent this, the removal of the adhesive requires a lot of time and cost.
