Consists of a first parallel layer composed of a bamboo-like board or bamboo-like small timber and a second parallel layer composed of a wooden board or small-wooden timber, and a bamboo-like board or small bamboo-like timber Comprising a first orthogonal layer,
An orthogonal assembly plate, wherein the second parallel layer is disposed between the first parallel layer and the first orthogonal layer, and the first parallel layer is an outermost surface layer. An orthogonal assembly plate formed by laminating and bonding parallel layers and orthogonal layers made of wood,
An orthogonal laminated board characterized in that a resin board containing bamboo fibers is arranged on the surface.   An orthogonal laminated board made by laminating and bonding a parallel layer made of bamboo-like board or bamboo-like small timber and an orthogonal layer made of bamboo-like board or bamboo-like small timber.
