It is possible to obtain excellent adhesive strength even under low temperature and short time curing conditions, and to maintain excellent performance even after a reliability test (for example, left at 85 ° C. and 85% RH). The present invention also provides an adhesive composition having excellent storage stability. An adhesive composition containing (a) a thermoplastic resin having a urethane bond and an ester bond in the same molecule, (b) a radical polymerizable compound, and (c) a radical polymerization initiator. The adhesive composition is characterized in that it contains two or more types of the above-mentioned (a) thermoplastic resins, and the glass transition temperature of at least one of the above-mentioned (a) thermoplastic resins is 40 ° C. or lower.
