    Abstract: An object of the present invention is to obtain a shaped steel beam having a strong bonding force with respect to concrete, and to obtain a wall with a reduced thickness. An H-beam has a plurality of projections on an inner face, and satisfies the conditions P/h?10 and P/b2?4, where b2 represents the upper-side width of the projections, h represents the projection height, and P represents the projection pitch in a cross section perpendicular to the inner face having the projections. A wall uses the H-beam as a structural member. In the wall, H-beams stand at a plurality of positions in the longitudinal direction of the wall with outer faces of flanges pointing toward the surface of the wall.
