To provide a low-vibration type saw blade for grinding or cutting a material to be ground which consists of a hard brittle material such as a stone, in particular, a super-hard brittle material such as a tile.

In the low-vibration type saw blade, a super-abrasive grain layer consisting of diamond abrasive grains or CBN abrasive grains is formed on an outer circumferential edge of a circular steel substrate. In a pair of male and female flanges formed of fiber reinforced plastic as a material, a mounting hole for an electric tool spindle is formed at the center portions. The pair of male and female flanges are integrally attached to a substantially 1/2 portion of the steel substrate in its outer circumferential direction via a center hole formed at the center of the steel substrate, so as to be held from both sides of the substrate.
