To manufacture a wooden member rich is design properties at a low cost by a method wherein the surface of a wooden material is coated transparently and, after that, chipped randomly so as to produce a minute unevenness.

By bonding wood pieces 10a-10d to one another, a laminated material 10 having a shape in response to its use application is manufactured. The surface of a pattern forming object in the laminated material 10 is applied with a transparent primer coat and, after being dried, colored. Further, after a colorant is dried, the colorant is chipped locally and randomly in various widths and in various depths. This depth changes in response to the coating thickness of the colorant such as 1-400 μm. In this case, a colorant chipping process is performed by rotating a roller brush, which is formed by providing a large number of metal wires projected randomly beyond its periphery, is rotated under the state being urged against the colored surface and, at the same time, by advancing the laminated material 10. And, minute unevenness are produced at random, resulting in developing a diffused reflection. Thus, a wooden member plenty of design properties can be manufactured at a low cost.
