The particleboard of single-layer random was producted from the particle of cutting with the knife ring-flaker. Production factor such as specific gravities (SG), resin content (RC) and form of the particle relation of mechanical properties of particleboard was examined. The results were summarized as follows: 1) When SG is 0.65 or less, MOE increased attendant upon the increase length(gamma) of the particle. 2) In case of 5% RC, both MOE and MOR almost there is no difference in the value regardless of the form of the particle. On the one hand, when RC is made high up to 13%, the heterogeneous part of the material occurs inside the board, causes concentration of stress to the part of that. Because of that MOR is saturated in 13% RC. 3) The board which uses the particle whose width(omega) is narrow and length(gamma) is short, making RC high, showed the brittle destructive form where the lines of rupture irregularity are few. Because of that the revised effect of Wb for the increase of RC is not clear. 4) The board type whose thickness(delta) is thick as for IB becomes large. 5) With the board whose variation of width(omega) is large, gluing join becomes more complicated, that makes compressed stress distribute well.
