A formed ligneous body which has highly original and excellent design and exhibiting a novel handsome appearance, owing to properties of ligneous materials which can be given desired degrees of translucency by impregnation with resin materials and which are subjected to a flow molding process. Also disclosed is a method of producing the formed ligneous body. In the formed ligneous body employing resin-impregnated ligneous materials, produced through a flow molding process wherein heating and forcing are carried out, extrusion and flow molding are carried out at the same time and with an appearance surface on the surface, a translucent base portion and decorative spot portions whose degree of translucency is different from that of the base portion are formed in an integrated manner, the base portion and the spot portions are formed of respective resin-impregnated ligneous materials having respective different color tones, the base portion is formed with a predetermined thickness, while the plurality of spot portions are integrally embedded within and/or exposed on surfaces of the base portion in a predetermined pattern of local arrangement.
