    • PROBLEM TO BE SOLVED: To provide an adhesive composition for a wood having a low formaldehyde odor, which has excellent adhesion properties to a conifer veneer while maintaining productivity of a plywood obtained when an amino resin adhesive is used to a conventional broadleaf tree material and which achieves low temperature press and achieves production of the plywood even when water content of an applied veneer is high and to provide the plywood using the adhesive composition. SOLUTION: The adhesion composition for a wood contains 0.001 to 0.05 mol of one or more selected from among aluminum, an aluminum compound, iron, an iron compound, boron and a boron compound in 100 g resol type phenol resin having a weight average molecular weight (Mw) of 2,000 or more converted in terms of polystyrene measured by high speed liquid chromatography and molecular weight distribution having a dispersion (Mw/Mn) of 4 or less to be a ratio of weight average molecular weight (Mw) converted in terms of polystyrene measured by high speed liquid chromatography to number average molecular weight (Mn).
