A scribing wheel is composed of an outer circumference end section wherein a circumference ridge line is formed by having crossed bottom sections of two truncated cones which are sharing a rotating shaft, and a plurality of notches and protruding sections alternately formed in a circumference direction along the circumference ridge line. The protruding section is composed of a part of the circumference ridge line, which is left by notching the circumference ridge line and has a length in the circumference direction. The protruding sections are rotated by being brought into contact with a brittle material substrate with pressure, and scribe lines and vertical cracks extending in the thickness direction of the brittle material substrate are formed on the brittle material substrate. The length of the notch in the circumference direction is permitted to be shorter than that of the protruding section in the circumference direction, and catching (holding) to a glass surface is improved, while suppressing hyperosmotic effects.
