PROBLEM TO BE SOLVED: To provide a joint structure of precast composite floor slabs increasing connection strength of the joint structure and reducing cost of the joint structure. SOLUTION: This joint structure 100 of precast composite floor slabs including bottom steel plates 2a, 2b and reinforced concrete boards 4a, 4b having a plurality of reinforcing bars arranged like mesh and formed on the bottom steel plates to connect ends of the precast composite floor slabs is composed of a first structure constituted by letting end faces of the reinforcing bar concrete boards of the first and second precast composite floor slabs 1a, 1b oppose to each other across a clearance for placing concrete to fill it and positioning a plurality of end parts of the first and second reinforcing bars of the first and second precast composite floor slabs alternately within the clearance for placing concrete to fill it; a second structure constituted by inserting the ends of the first and second reinforcing bars into a plurality of through-holes formed in a steel belt-like reinforcing plate, respectively, and a third structure constituted by locking nut members 8b screw-fitted into a plurality of end parts of the first and second reinforcing bars into a first face and a second face on first and second precast composite floor slab sides in the belt-like reinforcing plate 7.
