PURPOSE:To provide a method for molding a wood product wherein a resin content is lowered, a wood product whose strength is uniform and high can be easily formed, and machining such as finishing working is not necessary. CONSTITUTION:A molding material 6, which is made by kneading 1 weight ratio or above of vegetable fiber material with 1 weight of thermosetting resin having a dielectric loss tangent of 0.01 or above, is injected into a formwork 3. The formwork 3 is laid on a lower plate 2 mounted on an up-and-down lower cylinder 1. An upper plate 4 mounted on an upper cylinder 5 is made to descend so as to press the formwork by a pressure of 8kg/ cm or below. Further, the lower plate 2 is made to be a positive electrode and the upper plate 4 is made to be a negative electrode so as to operate a high-fre quency dielectric heating device and set the molding material 6 in the formwork 3 with heat. Thus, an original form of a wood product which requires various forms and strengths can be obtained without machining, and the quantity of the resin is extremely lowered comparing with a conventional method, thereby obtaining a wood product light in weight.
