This study was investigated on the properties of board made from carbonized rice husk differed in density of board, resin addition ratio and sawdust addition ratio. Water absorption is showed the lowest value to 80.09% when the resin addition ratio of 25%, as the density increased and sawdust addition ratio decreased, the water absorption was decreased. The measured thickness swelling satisfied with the quality standards of KS F 3104, so the feasibility of building interior has been confirmed in the dimensional stability. In case of resin addition ratio of 25%, the internal bond strength was satisfied quality standards of KS F 3104 to $0.244N/mm^2$. With increasing the density, resin and sawdust addition ratio, brinell hardness increased.
