PROBLEM TO BE SOLVED: To reduce construction mandays and to prevent the increase of thickness while improving the bearing force of an earthquake resistant wall by embedding bracing reinforcements wound with spiral reinforcements, in concrete forming a wall body. SOLUTION: Bracing reinforcements 11 are arranged in X-shape four by four, for instance, and two bracing reinforcements 11, 11 are made a pair and wound with a spiral reinforcement 12. The reinforcements 11 are embedded almost in the center of the width of concrete 13. An earthquake resistant wall 1 with the built-in bracing reinforcements 11 wound with the spiral reinforcements 12 can exhibit sufficient structural performance since buckling of the bracing reinforcements 11 is suppressed by the spiral reinforcements 12, and moreover construction mandays can be reduced in comparison to an earthquake resistant wall using conventional bracing members. In the case of the earthquake resistant wall 1 being used as a separation wall of a house, there is no need to cover it with fireproofing material, which prevents the increase of thickness of the earthquake resistant wall 1.
