摘要： A diamond saw blade D includes diamond grinding stones 2 attached to the peripheral edge of a circular base plate 1. When a first value obtained through multiplication of the circumferential length of a circle having a diameter equal to the maximum outer diameter of the diamond saw blade D by the maximum thickness t of the circular base plate 1 is compared with a second value which is the total area of end surfaces e of the diamond grinding stones 2, the ratio of the second value to the first value is not less than 0.3 but not greater than 1.0.
