PROBLEM TO BE SOLVED: To provide precast SRC column joint part structure for easily jointing precast SRC columns to each other in a short time, improving construction accuracy and stability in construction and acquiring firm joint structure with comparatively simple low-cost member constitution. SOLUTION: A steel frame projecting part 11 of prescribed length is formed by projecting a steel frame 2 of the precast SRC column 1 of a lower floor from a joint end face, and a recessed part 16 is formed at a lower end part of the steel frame 2 of the precast SRC column 1 of an upper floor by a base plate 12 and a cylindrical shear connector 13. The steel frame projecting part 11 is inserted in the recessed part 16 and integrated by filling high-strength mortar grout 14 in a clearance. Further, the joint end parts of upper and lower column main reinforcements 3, 3 are inserted in a sleeve joint 15 embedded in the joint end part of the precast SRC column 1 of the upper floor, and integrated by filling high-strength mortar grout 14.
