PROBLEM TO BE SOLVED: To provide a column-to-beam junction structure in which junction of a column to a beam is simple, in which work mandays are reduced, in which cost is low, in which out-of-plane durability of a beam end is high compared to a conventional outer diaphragm method, and in which charge performance of concrete, if any is charged, can be securely assured. SOLUTION: A long cylindrical member in which a column A can be inserted and engaged is cut in a specified length, a right and a left flanges of a member having an H-shaped cross section are welded to be parallel to an axis of the cut cylindrical member to form a connection metal 6, the connection metal 6 is inserted into a junction part 4a of the column A to which a beam B is jointed to be welded, and flanges of the H-beam B are fixed to webs of the member having the H-shaped cross section in the connection metal 6.
