This study was carried out to get some basic information on mechanical properties of Korean Lepidobalanus for the rational utilization of their woods, Five species of Quercus variabilis, Q. aliena, Q. serrata, Q. mongolica, Q. acutissima belonging to Lepidobalanus were investigated in this research. Relationship of anatomical characteristics with bending strength was analyzed using stepwise regression technique. All possible combination of 21 independent variables were regressed on bending strength. The summarized results in this study were as follows: 1) In the proportion of wood structural elements, the most important factors on bending strength appeared to be proportion of wood fiber in earlywood in Q. variabilis and Q. serrate, proportion of ray in earlywood in Q. aliena, proportion of vessel in earlywood in Q. mongolica and proportion of wood fiber in latewood in Q. acutissima, respectively. 2) In the other quantitative anatomical characteristics, the most important factors on bending strength appeared to be number of pore per $1mm^2$ in latewood in Q. variabilis, microfibril angle in Q. aliena and Q. mongolica, length of wood fiber in Q. serrata and height of uniseriate ray in Q. acutissima, respectively.
