PROBLEM TO BE SOLVED: To provide a processing apparatus of a band saw, a processing method of the band saw and the band saw by which successful rolling processing of a weld zone by a simple operation. ! SOLUTION: A processing apparatus A which performs rolling processing of a weld zone 31 of a band saw 30 annularly formed by welding both ends is provided with an upper side roll 18 and a lower side roll 17 installed in a vertical direction by making rotational axes 14c, 16c in parallel with each other. Then, the processing apparatus A is constituted so that the band saw 30 moves in a width direction along a longitudinal direction of the weld zone 31 by making a circumferential direction of the band saw 30 along axis directions of the upper side roll 18 and the lower side roll 17, installing the band saw 30 between the upper side roll 18 and the lower side roll 17, and rotating the lower side roll 17. !
