SOLUTION: This floor slab form 1, which is made of a metal steel plate with rust resistance and corrosion resistance, includes a bottom plate portion 3, and first and second side wall portions 6 and 7 and third and fourth side wall porions 10 and 11, which are provided at the peripheral edge of the bottom plate portion 3. The inside of the form includes a plurality of reinforcing steel materials 13, and a plurality of auxiliary reinforcing steel materials 14 which cross the reinforcing steel materials 13; the third and fourth side wall porions 10 and 11 include first and second wall plate portions 18 and 19; and a plurality of radial reinforcement groups 20 and a first horizontal reinforcement 21 are provided between the first and second wall plate portions 18 and 19.
