PROBLEM TO BE SOLVED: To provide a composite steel floor slab using rubber latex mortar, which brings about the high bonding strength of a steel plate and a rubber latex mortar layer. SOLUTION: This composite steel floor slab using the rubber latex mortar is characterized in that: the surface roughness Rz of a steel plate surface is in a range of 60-150 μm; and a polymer/cement ratio (P/C) of the rubber latex mortar is in a range of 9-30 wt.%. For example, when horizontal shearing stress which is generated on a boundary surface between the steel plate surface and the rubber latex mortar layer due to bending deformation is 2.0 N/mm<SP>2</SP>or larger, the mortar layer has the bonding strength high enough to prevent separation from the steel plate surface.
