PROBLEM TO BE SOLVED: To provide a bearing wall with a high and stable shearing resistance using one sheet of steel plate by improving the shape of the bearing wall. SOLUTION: A frame part formed in a U-shape or L-shape in cross section by bending the four ends of one sheet of rectangular steel plate and a surface plate part which has an opening part with the four ends and a plurality of diagonal parts and edge walls provided to the all the peripheral edges of the opening and in which the opening part is formed symmetrically in the upward and downward directions and in the leftward and rightward directions are made of one sheet of steel plate. Since the frame part does not need to be joined to the surface plate, the lightweight bearing wall with a stable shearing resistance can be manufactured at low cost without causing the deterioration of environment due to welding, without increasing auxiliary devices and materials and labor due to the fixing of drill screws.
