To enable sawing in a center stabilized state by providing M-shaped double teeth on the sawtooth side in a saw blade for a sawing machine, and distributing several respective second teeth of the double teeth so as not to project by going over the saw blade side surface.

In a saw blade 10 for a vibratory sawing machine, double teeth 18 having respectively two edges 17, 19 on the sawtooth side 20 are alternately distributed to one side surface and the other side surface so that the respective sawteeth 18 are set in two stroke directions in the mutually inverse direction. The edges 17, 19 of undistributed second double teeth 18a of the respective double teeth 18 are projected outside or downward more than the edges of the distributed double teeth 18 when viewed from the saw blade 10 side surface, and the respective double teeth 18a are distributed so as not to project by going over the saw blade 10 side surface. Therefore, notching of the saw blade 10 into a workpiece can be easily performed by generating the center stabilizing action.
