PROBLEM TO BE SOLVED: To provide a method for easily producing a joined product having increased joining reliability, and to provide a joined structure having increased joining reliability. SOLUTION: The edge part to be joined in a hollow joining member B (rib-fitted hollow extruded shape 14) in which a plurality of ribs 24a, 24b are formed is inserted into a space between planar flange parts 16a, 16b parallelly elongating so as to be confronted each other in a joining member A (flange-fitted extruded shape 12), the flange parts 16a, 16b in the joining member A and the upper and lower face sheet parts 20a, 20b in the hollow joining member B are mutually lapped, thereafter, the probes of a friction stir joining tool are inserted into the respective projecting parts 30 provided at the outer surfaces of the parts disposed with the ribs 24a, 24b in the upper and lower face sheet parts 20a, 20b through the flange parts 16a, 16b, and are moved along the respective projecting parts 30, and the joining member A and the hollow joining member B are subjected to lap friction stir joining, so as to produce a joined product 10.
