The tactile feeling is important in product development because it influences the consumer's willingness to buy. In particular, the tactile sensation depends on the surface properties such as the spacing and height of the texture convexity, and texture design has attractive attention. Decorative treatments are one of texture design method. In some cases, due to performance or physical limitations of the material itself, material may be used to represent the target material and the surface is decorated for imitation. In this study, we focused on the tactile imitation of wood by resin print, which is one of the decorative treatments, and clarified the relationship between the surface properties of resin-printed samples and human perception of material texture. We conducted sensory evaluation experiments on resin-printed samples to clarify types of sensations that contributes to a sense of wood and investigated the relationship between the amount of sensation and the sensor output. As a result, it was suggested that roughness contributes to the sense of wood, and that the sense of wood may increase as the roughness increases.
