Abstract

PURPOSE:To inhibit warpage easy to be generated in fitting by making the directions of groove sections extended in the longitudinal direction extending over the entire length in a large number of base materials, in which the groove sections are formed to one surface on the long sides of a long-sized woody material having a rectangular cross section, irregular and combining the base materials. CONSTITUTION:In a fitting backing board, a plurality of base material 3, in which groove sections 2 are formed to a long-sized woody material having a rectangular cross section, are joined and shaped while the groove sections 2 are directed at random up and down and left and right and forward and rearward. In the base material 3, the groove sections 2 extended in the longitudinal direction extending over the entire length are recessed in one surface on the long side, and a surface opposite to the direction that the base material 3 is easy to warp is used as one surface in which the groove sections 2 are formed. Both short sides of the base materials 3 are aligned, the groove sections 2 are directed left and right, and three base materials 3 are bonded by using adhesives, etc., thus forming vertical frame materials 5, 5 on both sides. A large number of the base materials 3... having the same length are laid horizontally between the frame materials 5, 5 while each groove section 2 is directed toward an upper section or a lower section, thus forming the rectangular fitting backing board 1. Accordingly, warpage easy to generat in the woody material is inhibited, thus forming fittings having excellent quality.
