PROBLEM TO BE SOLVED: To highly stabilize a size at the time of absorbing water and moisture by dipping lignocellulose fiber of woody fiber or the like in a hot water of a specific temperature to dissolve to remove hot water soluble components, then dispersing an adhesive, applying a heat and a pressure to mold it in a plate-like state. SOLUTION: The fiber plate obtained by dipping lignocellulose(LC) fiber of a woody fiber or the like in a hot water of 80 deg.C or higher to dissolve to remove hot water soluble components, then dispersing an adhesive, applying a heat and a pressure to mold it in a plate-like state is reduced in components easy to absorb moisture in the plate by the hot water dipping. If the hot water temperature is lower than the 80 deg.C, the soluble component amount to be dissolved and removed is low, and the much components easy to absorb the moisture remain in the fiber. The LC fiber of the plate contain a cellulose and a lignin as main components and is a fiber from a conifer, a broad-leafed tree, a coconut, a hemp, a bamboo, a rice plant or the like. As the adhesive at the time of thermoforming, a urea, melamine, urethane or the like resin to be thermoset is used. Thus, dimentional stability at the time of absorbing water or moisture can be improved by a simple method.
