Zusammenfassung:	A phenol resin-impregnated sheet 1 formed by impregnating a porous resin sheet with a phenol resin having a degree of cure of 70% or more and 95% or less is disposed and laminated on the surface of a carbon fiber-reinforced thermosetting resin sheet 2. When the thickness of the phenol resin impregnated sheet 1 is 0.01 mm or more and 1.0 mm or less, a wood reinforcing material with no unevenness and no curling and water proofness and strength can be obtained. The wood reinforcing material is integrated and cured on the surface of the wood material by way of the phenol resin-impregnated sheet 1 to reinforce wood material (single board or bonded board) to form a reinforced wood material. The wood reinforcing material is able to adhere with the wood material and in the handlability, results in no environmental contamination which would cause wastes such as release paper and has sufficient reinforcing effect to the wood material.
