An adhesive composition of the present invention comprises (A) a conjugated diene polymer having a weight-average molecular weight of 500 to 100,000 and (B) an electron pair-donating basic compound; or comprises (A) A conjugated diene polymer having a weight-average molecular weight of 500 to 100,000, (C) a compound having in its molecule three or more functional groups selected from the group consisting of acryloyloxy group, methacryloyloxy group and groups represented by the following formula I:
1
wherein R
1
, R
2
and m are the same as defined in the specification, and (D) a compound having in its molecule one or two functional groups selected from the group consisting of acryloyloxy group and methacryloyloxy group. At least a part of the surface of an adherend is coated with the adhesive composition to form an adhesive layer. After optionally irradiating the adhesive layer with ultraviolet light or radiation, the vulcanization is preformed while bringing an unvulcanized rubber into press-contact with the adhesive layer, thereby attaining a strong adhesion between the rubber and the adherend. The rubber/adherend composite thus produced is suitably used for the production of rubber-reinforcing materials and rubber articles.
