PURPOSE:To obtain an adhesive composition exhibiting an excellent adhesion in bonding a rubber to a metal and no significant lowering in adhesion even after heat deterioration, by incorporating a dithiocarbamate and a petroleum resin in principal agent for adhesive comprising a chlorinated polymer as a main component. CONSTITUTION:In a main component comprising a chlorinated polymer such as a chlorinated polypropylene, a vinyl chloride elastomer, etc. are incorporated carbon black, a crosslinking agent, etc. to obtain a principal agent for adhesive. 100pts.wt. (on a solid basis) principal agent for adhesive is mixed with 2-20pts. wt. dithiocarbamate (e.g.: nickel dibutyldithiocarbamate or nickel di ethyldithiocarbamate) and 100pts.wt. or less petroleum resin to obtain an intended adhesive composition. The petroleum resin is an adhesive resin compris ing a polymer of styrene, vinyltoluene, etc., and containing an aromatic hydrocar bon and a polycyclic hydrocarbon as a main component.
