PROBLEM TO BE SOLVED: To provide a precast concrete slab capable of reducing cost while having sufficient rigidity. SOLUTION: This precast concrete slab is constituted so as to fix a fixing part 4 fixed to a building beam material by appearing on the outside edge of a concrete floor slab 1 to both end parts of a horizontal brace 2, by embedding the horizontal brace 2 inside the concrete floor slab 1. Thus, the horizontal brace 2 can be joined to and arranged on the building beam material together with the concrete floor slab 1 by joining the concrete floor slab 1 to the building beam material via the fixing part 4. As a result, the sufficient rigidity can be provided as the concrete floor slab 1. Since work at an elevated spot is facilitated more than when arranging the horizontal brace 2 separately from the concrete floor slab, workability is improved, and the cost can be reduced.
