PROBLEM TO BE SOLVED: To provide a hot-melt adhesive composition which combinedly has antinomic properties, namely fluidity at high temperatures and excellent heat- resistant flowability, is low in the surface tack at room temperature, and capable of repeatedly reproducing adhesion curing and fluidity to easily enable recycle utilization of adherends. SOLUTION: This hot-melt adhesive composition comprises 20-90 wt.% polymer having a reactive site capable of forming a hydrogen bond and a compound having two or more reactive sites capable of forming a hydrogen bond with the reactive site of the polymer with an equivalent ratio of the donor of -OH and/or -NHR (wherein, R is hydrogen, an alkyl group, an aryl group or an acyl group) to the acceptor of a tertiary amino group and/or a carbonyl group of >=0.1 as the combination of the reactive sites.
