<P>PROBLEM TO BE SOLVED: To provide a reinforcement joint which achieves an improvement in workability in a factory and on a job site, reduction in filling mortar and manufacturing costs, and reduction in the length and weight of the reinforcement joint. Ž<P>SOLUTION: The reinforcement joint 10 for serially connecting two reinforcements is formed in such an approximately tubular shape as to have a closed end 3, an opening end 2 and a tubular body portion 1. The reinforcement joint 10 includes: a mortar inlet 5, which communicates with a gap 4 between an inner surface of the reinforcement joint and the reinforcement inserted from the opening end, for infilling the mortar infilled into the gap; and a mortar-discharge checking opening 6 which communicates with the gap, and which enables checking of the infilling of the mortar into the gap. The reinforcement joint is fixed in such a way that an outer surface of the closed end and an end of the one reinforcement 7a are joined to each other by welding, while the other reinforcement 7b is inserted into the opening end, and the mortar is filled into the gap.
