Circular saw blade

A circular saw blade in which cutting teeth are joined to a plurality of tooth bodies projecting outward in a radial direction at a plurality of locations on an outer periphery of a disk-shaped metal base, gullets are provided between the plurality of tooth bodies so as to be recessed in the radial direction, radial clearance angles of side cutting edges of the cutting teeth are greater than −1° and less than 1°, and a vibration prevention mechanism for preventing vibration of the metal base itself is provided, wherein

• depths of the multiple gullets are at least partially different, and a ratio of a difference between a maximum value and a minimum value of average values of depths of the adjacent gullets to an average value of the depths of the gullets is 20% to 100%.
