The present invention is to provide a gypsum-based load-bearing board for wood structural load-bearing walls which is capable of increasing the co-efficient of effective wall length without additionally using reinforcement materials or stiffening materials, and without increasing the specific gravity and/or the thickness of the gypsum-based load-bearing board. The gypsum-based load-bearing board for wood structural load-bearing walls includes a main member or a core member formed from a board-shaped hardened gypsum containing an inorganic fiber and an organic-based strength enhancer that exert a lateral nail resistance of 500 N or more, and a paper covering at least front and back sides of the main member or the core member to constitute the load-bearing board.
