PROBLEM TO BE SOLVED: To provide an economical precast concrete bearing wall easy to manufacture, and a multistory bearing wall structure easily constructed using the bearing wall not by a filling type sleeve construction method. SOLUTION: The precast concrete bearing wall is provided with a plurality of vertical reinforcements 20 formed of deformed reinforcements disposed forming projecting parts 21, 22 at both upper and lower ends of a wall body 10 of the precast concrete bearing wall, and horizontal reinforcements 30, 31 orthogonal to the projecting parts 21, 22 of the vertical reinforcements. The horizontal reinforcements 30, 31 are jointed to the vertical reinforcements 20 by welding at the projecting parts 21, 22 of the vertical reinforcements. The projecting parts 21, 22 of the vertical reinforcements and the horizontal reinforcements 30, 31 are anchored within the thickness h3 of a floor slab 50. The projecting part 22 of the vertical reinforcement on the lower side of the upper story precast concrete bearing wall 1, and the projecting part 21 of the vertical reinforcement on the upper side of the lower story precast concrete bearing wall 1, form a vertical overlap part o within the thickness of the floor slab. A plurality of horizontal reinforcements 30, 31 are arranged in square grated shape at the projecting parts 21, 22 of the vertical reinforcements and located at the overlap part o.
