Abstract
A simulated wood tone member having good gradation (shading) of a wood grain pattern, and a method of manufacturing the simulated wood tone member are provided. Recesses 11 of different depths (h1, h2, h3) are formed in a surface of a urethane based base member 16 which is molded in a mold 30 in which a wood grain pattern is formed by etching in plural stages. As a result, gradation of a pattern can be expressed by the recesses 11 in the surface of the urethane based base member 16. Then, by filling a wood filler 21, which is transparent and contains a coloring agent, into the recesses 11, the gradation can be varied in accordance with the depths of the recesses 11. A wood grain pattern having an attractive wood appearance can be obtained.
