Provided is a rolled H-section steel having a web and flanges. The rolled H-section steel satisfies the following Expression (1) when H is the height of the rolled H-section steel, and B is the breadth of the flanges. The tensile strength is 400 to 510 N/mm2. The rolled H-section steel satisfies the following Expressions (2) and (3), when the plate thickness of the flanges is t2, and the design yield stress of a steel material of the rolled H-section steel is F(N/mm2).
