Properties of wood powder pulverized by a vibration were evaluated. In the previous paper, it was clarified that the wood biomass was able to be pulverized into micron order particle by a vibration mill equipped with rods and balls. In this paper, characteristics of wood powder, such as particle diameter, particle shape, aspect ratio, specific surface area, crystallnity and equilibrium moisture content, was measured. As the results, it was found that the vibration mill was available for the production of wood powder, which has big surface area and low crystallnity.
