PROBLEM TO BE SOLVED: To provide a connecting structure preventing the infiltration of water caused by a capillary tube phenomenon or a deformation caused by the composite action of the tensile force and shearing force applied to buried reinforcing bars at a junction of a steel product and concrete forming a truss structure. SOLUTION: This connecting structure connects the steel product SP to a concrete slab or a beam P. The steel product is connected to the slab or the beam, and the end section of the steel product is vertically welded to a metal plate 1. This connecting structure for the steel product and concrete in a truss structure comprises the metal plate provided with projections 2 having the same cross sectional shape as the end section of the steel product on one face 1a and a plurality of opening sections 3 each having a screw groove on the opposite face 1b so that the projection and a plurality of opening sections are provided on the inside than the outer edges of one face and the opposite face, a plurality of reinforcing bars 4 each having a screw at one end 4a, screwed to the screw groove provided in each opening section of the metal plate, and fixed to the arranged bar of the slab or the beam at the other end 4b, and lock nuts 5 each for fixing the reinforcing bar at the prescribed position after one end of the reinforcing bar is screwed into the opening section of the metal plate.
