2. Description of the Related Art Conventionally, an organic silane-based adhesive has been mainly used for bonding various resins to fluororubbers. If there is a problem with water resistance, and if the secondary vulcanization temperature of the fluororubber is 200 ° C or higher, hydrogen fluoride generated from the fluororubber often causes peeling on the resin-bonded surface. Peeling often occurs even in a water environment such as water.

The present inventors have previously proposed a vulcanized adhesive composition containing a novolac type epoxy resin, a novolac type phenol resin and a curing agent therefor (Japanese Patent Laid-Open No. 62-14).
1082). This vulcanized adhesive composition shows the effect of effectively preventing peeling on the metal-bonded surface due to hydrogen fluoride, which was observed when the metal and the fluororubber, which were also used for the organosilane adhesive, were bonded. Therefore, I tried to use this vulcanized adhesive composition as it was for the adhesion between the resin and the fluororubber. Although the problem was overcome in terms of heat resistance, only an adhesive having poor hot water resistance was obtained.
