PROBLEM TO BE SOLVED: To provide an aqueous adhesive composition with biodegradability, which forms an adhesive layer without infiltrating inside even in the case of a wood adherend, and exhibits an excellent adhering property. SOLUTION: The adhesive composition comprises a principal ingredient composed of a polylactic acid emulsion, an aqueous polymer and a filler, and a curing agent composed of a polyamide epoxy resin. The principal ingredient comprises 0.2-45 wt.% of the polylactic acid emulsion as the solid content, 4-56 wt.% of the aqueous polymer as the solid content and 5-55 wt.% of the filler. The curing agent of the amount of 0.2-40 pts.wt. is contained in 100 pts.wt. of the principal ingredient. COPYRIGHT: (C)2008,JPO&INPIT
