Provided is an adhesive composition that provides excellent adhesion between a thermoplastic resin or a thermoplastic elastomer in which an elastomer component is dispersed in the thermoplastic resin and a tire by a combination of general-purpose materials, without using any special polymer. The adhesive composition comprises 100 parts by weight of a base polymer and 20 to 50 parts by weight of a resol-type phenolic resin-based resin crosslinking agent, wherein 100 parts by weight of the base polymer comprises 80 to 99 parts by weight of a thermoplastic elastomer and 1 to 20 parts by weight of a halogenated rubber. The resol-type phenolic resin-based resin crosslinking agent is preferably an alkylphenol-formaldehyde resin. Examples of the thermoplastic elastomer can include styrene-butadiene-styrene block copolymers, and examples of the halogenated rubber can include chloroprene rubber and chlorosulfonated polyethylene.
