PROBLEM TO BE SOLVED: To obtain the subject adhesive composition having such advantages that, in bonding operations for secondary processed plywoods such as sliced veneers, the setting time range until sliced veneer sheet laminating is wide; in this case, there is good workability enough to stand some corrections by handwork; adhesive force is developed quickly after bonding and enhanced with time; and even the highly severe requirements as specified in JAS Class I can be met. SOLUTION: This adhesive composition comprises (A) 60-98 wt.%, on a solid basis, of an ethylene-vinyl acetate copolymer resin emulsion and (B) 40-2 wt.%, on a solid basis, of an amino resin adhesive; wherein the component A to be preferably used is such one as to be 5-30 wt.% in ethylene content and prepared by a well-known method by emulsion polymerization under an autoclave pressure of 20-100 kg/cm2 using normally polyvinyl alcohol or the like as protective colloid in the presence or absence of nonionic and/or anionic surfactant(s); and the component B to be preferably used is e.g. a melamine-formaldehyde resin adhesive, urea-formaldehyde resin adhesive, being such one as to be prepared by a well-known method.
