PROBLEM TO BE SOLVED: To provide a band saw which can smoothly perform discharge of chips or supply of polishing liquid, obtains excellent cutting sharpness, reduces machining damage to a workpiece, and obtains excellent surface roughness. SOLUTION: The band saw 100 includes a plurality of abrasive layer fixed to a base metal at an interval, and is equipped with a band like flat shape base metal 1; a first blade part 11 which is provided on one side of two end edge parts 1E, 1F extending to the longitudinal direction of the base metal, and is fixed with a first abrasive layer 11A having a first cutting edge width w<SB>1</SB>on the front surface 1S and a back surface 1T of the base metal 1; a second blade part 12 which is provided on the one end part 1E having the first blade part 11 adjacent to the first blade part 11, and is fixed with a second abrasive layer 12A having a second cutting edge width w<SB>2</SB>different from the first cutting edge width w<SB>1</SB>on the front surface 1S and the back surface 1T of the base metal 1.
