PROBLEM TO BE SOLVED: To provide a saw blade manufacturable at low cost and reducible in cutting noise. SOLUTION: This saw blade includes a plurality of saw teeth 19S, 19L, 19R for cutting the entire width W of a cutting groove 17 formed in a work WP for a plurality of divided widths W1, W2, W3, respectively, when the work WP is cut by the saw blade 15. The saw blade has, as set patterns, a plurality of saw teeth 19S, 19L, 19R corresponding to the divided widths W1, W2, W3, respectively. An addendum pitch pattern PT formed in predetermined repeated patterns is formed in the saw blade 15 by having the plurality of set patterns. Where pitches of the saw teeth with the same functions for cutting the same divided widths in the plurality of set patterns formed in the addendum pitch pattern PT are addendum functional pitches, the addendum functional pitches are different from each other. The set patterns includes right and left set teeth 19L, 19R set in the lateral direction. The saw tooth pitches P1-P9 in the set pattern are different from one another. COPYRIGHT: (C)2010,JPO&INPIT
