PROBLEM TO BE SOLVED: To provide a manufacturing method of a wooden formed board employing a thermal crosslinking aqueous acrylic resin therein, in which drastic reduction in forming time is achieved and flexural strength, wet flexural strength and water-absorbing swelling coefficient of a board are improved. SOLUTION: This wooden formed board is formed by uniformly blending (A) a polymer obtained through radical polymerization, the 5-100 wt.% of which comprises an ethylenic unsaturated acid anhydride or an ethylenic unsaturated dicarboxylic acid, the carboxylic acid group of which can form an acid anhydride group and (B) 1-50 pts.wt. (in terms of resin) of a thermal crosslinking aqueous acrylic resin as a forming adhesive which is an alkyl amine having at least two hydroxy groups acting as crosslinking component with 100 pts. wt. of a wooden forming board stock under the condition that heating plate heating and high frequency induction heating or microwave heating are employed in combination for hot press forming after the blending.
