PROBLEM TO BE SOLVED: To provide a wooden building material which has high strength in all directions, looks high-class due to a solid appearance, and can keep costs low.SOLUTION: A core material 3 is arranged so that the lamination direction (A-B direction) of LVL 3a intersects with the lamination direction (C-D direction) of LVL 3b and 3c. Thus, when a wooden building material 1 is used as a pillar, the LVL 3b and 3c exert a large strength against force (force in the A-B direction) that tends to buckle the wooden building material 1 and the LVL 3a exerts a large strength against force (such as force in the C-D or E-F direction) that tends to laterally bend the wooden building material 1. This makes it possible to create a structural material having large strength in all directions, as it were.SELECTED DRAWING: Figure 2
【課題】全方向に対し大きな強度を有し、しかも外観が無垢材で高級感があり、且つコストを低く抑えることが可能な、木質建材を提供する。【解決手段】芯材３はＬＶＬ３ａの積層方向（Ａ−Ｂ方向）とＬＶＬ３ｂ、３ｃの積層方向（Ｃ−Ｄ方向）が交差するように配置されているので、木質建材１を柱として用いた場合、この木質建材１を座屈させようとする力（Ａ−Ｂ方向の力）に対してはＬＶＬ３ｂ、３ｃが大きな強度を発揮し、木質建材１を横方向へ曲げようとする力（例えばＣ−Ｄ、Ｅ−Ｆ方向の力）に対してはＬＶＬ３ａが大きな強度を発揮する。従って、いわば全方向に対して大きな強度をもつ構造材を実現することができる。【選択図】 図２
