The adhesive composition and the bonding method

A fast-curing high adhesion and seconds at durability test including a high-temperature high-humidity test, provides an adhesive composition that exhibits a high retention rate. (A) acrylonitrile content 10-30% nitrile butadiene rubber, containing (B) a polymerizable (meth) acrylic liquid composition, a basic compound having a (C) an organic peroxide, and (D) an amine structure a first agent, be a reaction condensate, and (F) the adhesive composition of two-pack type characterized by comprising a second agent containing a reducing agent containing copper (E) amine and aldehyde preferably, the adhesive composition characterized in that it contains a photopolymerization initiator in the first liquid, the joining method using the same.
