Abstract
A band saw blade includes left and right set teeth which are set in right and left directions with respect to a running direction of the band saw blade, and a straight tooth which is not set. A ridge line at a tip of each of the set teeth and the straight tooth is formed into a convex curved line protruding most at a central portion in a thickness direction of the saw tooth. The ridge lines at the tips of the left and right set teeth and of the straight tooth are continuous with one another when viewed from the running direction of the band saw blade. A height difference between the ridge lines of the saw teeth is in a range of 0.02 mm to 0.1 mm. Meanwhile, a height difference between an inner corner portion of each of the left and right set teeth and the central portion in the thickness direction of the ridge line of the straight tooth is in a range of 0 mm to 0.03 mm.
