[PROBLEMS] To balance the properties of wood materials such as bending strength, wet bending strength, water absorption thickness expansion rate and peel strength, while being excellent in compatibility of the components and capable of bonding at relatively low temperatures. The present invention provides a water-based adhesive composition useful for improving well, and a woody material obtained using the water-based adhesive composition. (A) a saccharide, (B) a water-soluble synthetic resin, and (C) an inorganic acid ammonium salt, wherein (C) the inorganic acid ammonium salt is at least selected from ammonium dihydrogen phosphate and ammonium chloride. It is the composition for water-system adhesion | attachment containing 1 type. (B) It is preferable that water-soluble synthetic resin contains a polyvinyl alcohol-type compound. [Selection figure] None |
