Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a composite floor slab which has excellent resistance to excessive shear force imposed on the floor slab, without setting shear reinforcements on the same. SOLUTION: The steel/concrete composite floor slab D is formed of a steel plate 1, concrete 4 placed on the steel plate, and headed studs 2, 3 each having a lower portion thereof joined to the steel plate 1 and functioning to prevent deviation of the concrete, and has haunch portions at least in two directions. According to the structure of the composite floor slab, an axial direction of each headed stud is diagonally arranged with respect to a cross sectional neutral axis of the concrete, or alternatively the headed stud has an irregular-shape shaft portion, and therefore the headed stud exerts a shear resisting function of the composite floor slab.
