Abstract

A compressed wood product includes a wood whose shape is taken while a volume decreased by compression is previously added, a direction intersecting a fiber direction (L) of the wood is set to a compression direction, and the wood is formed by being subjected to compressive force. For example, a wood (1-1) is obtained which includes a main plate portion (1a) in which a surface emerging in a thickness (W1) direction has a flat-grain surface and a side plate portion (1b) provided while rising from the main plate portion (1a). The shape of the main plate portion (1a) is taken with a thickness (W1) to which the volume decreased by the compression is previously added, and the shape of the side plate portion (1b) is taken with a thickness (W2) and a height (T1) to which the volume decreased by the compression is previously added. The direction (M) in which grains (G) are laminated and the direction intersecting the fiber direction (L) are set to the compression direction with respect to the wood (1-1), and the wood (1-1) is subjected to the compressive force.

Description
