PROBLEM TO BE SOLVED: To provide a heat-sensitive adhesive composition exhibiting a gelatinous state free from adhesivity at or below normal temperature and having adhesivity after heating at or above a prescribed temperature without forming gel even at normal temperature. SOLUTION: The heat-sensitive adhesive composition is composed of (a) a gelling agent composed of an optically active amino acid derivative expressed by general formula (I) and (b) a thermoplastic resin having a glass transition temperature of≤-20°C. In the formula (I), R<SB>1</SB>is a 1-7C alkyl or benzyl; (n) is 1 or 2; R<SB>2</SB>is an 8-30C alkyl or an alkylaryl composed of an aryl group having a 6-24C alkyl group when (n) is 1 and R<SB>2</SB>is a 4-30C alkylene when (n) is 2; and X is a protective group of an amino group.
