SOLUTION: The floor plate material 1 is provided with a plate material 2 formed by extrusion molding a material containing a resin and with a plurality of cavity parts 3 which are extended in the extrusion direction of the plate material 2 and are formed at prescribed intervals in the width direction of the plate material 2. At least a cavity part 3b of one among these cavity parts 3 is defined as an insertion part 4 into which the fixing material (for example a screw B) for fixing the plate material 2 is inserted. Inner wall surfaces at both sides for forming the insertion part 4 are provided with inclined parts 5 inclined in a way that the width of the insertion part 4 is made smaller in the insertion direction of the fixing material B and with fixing parts 6 which are respectively formed at top ends of the inclined parts 5 and fix the fixing material B by insertion of the fixing material B.
