Abstract
A first wooden surface layer and a second wooden surface layer are arranged in a mold, a core wire is arranged within the space defined by the first wooden surface layer and the second wooden surface layer, and resin introduced into that space. The first wooden surface layer and the second wooden surface layer are pressed against the inner surface of the mold by means of the internal pressure of the resin, thereby molding the first wooden surface layer and the second wooden surface layer. It is possible to obtain a molded article in which a wooden surface layer, a resin core and a core wire have been unitarily integrated without the production of cracks in the wooden surface layer.
