PROBLEM TO BE SOLVED: To provide a joint structure between a concrete filled steel pipe column and a flat slab for more reliably and sufficiently inhibiting bending moment from being applied to a steel pipe column resulting from the load of the flat slab than conventional while requiring lower cost, so much. SOLUTION: As an upper steel pipe 1 forming a steel pipe column portion at an upper hierarchy of adjacent upper and lower hierarchies of a steel pipe column 10, a steel pipe is adopted which has an outer diameter D1 smaller than an outer diameter D2 of a lower steel pipe 2 forming a steel pipe column portion at a lower hierarchy. In the joint structure A, A', B, or C, the upper and lower steel pipes 1, 2 are connected to each other via an upper steel pipe supporting plate 3 having a concrete through-hole 31, the flat slab 5 is installed on a stepped shelf portion S between the upper and lower steel pipes formed by connecting the upper and lower steel pipes to each other, and the load of the flat slab is supported mainly on the upper end face of the lower steel pipe.
