To enhance the function and strength of a reinforcement bar joint starting from the technical level and to reduce the cost in the manufacturing process of the reinforcement bar joint from the viewpoints of time, material and working cost.

In this method for manufacturing a reinforcement bar joint 5 for cross connection of two reinforcement bars 1, 2, the manufacturing process is performed by a progressive press. In the progressive press process, a spring steel band-made blank 10 is fed to the progressive press from the top in the progressive press process without being independently picked up every individual product, successively step-fed to each progressive press die, and successively molded while the vertical feed position of the blank 10 in each progressive press die of each progressive press is positioned to each progressive press die by a lifter pin 11P and a lifter pin hole 11N.
