PROBLEM TO BE SOLVED: To provide a method of placing a self-leveling material on backing surfaces of large difference in height at a time and a method of placing the self-leveling material thick in view of (1) the necessity to carry out a method of placing multiple times such as placing mortar or the self-leveling material beforehand on a backing part with an inclination, a recess, or the like, hardening and then placing the self-leveling material again in the case of placing the self-leveling material on the backing surface of different height or with a part having the inclination, recess, or the like, and (2) carrying out a method of placing in a plurality of times dividedly in the case of placing the self-leveling material thick. SOLUTION: In this construction method of a floor structure, aggregate is placed on the upper part of a backing layer, and slurry of the self-leveling material is placed once on the upper face of the backing layer to bury the aggregate, thus forming a hardened material layer of the self-leveling material on the upper face of the backing layer.
