Abstract
A double cone stylus includes a shank and a double cone-shaped tip attached to the tip end of the shank, the double cone-shaped tip being a rotationally symmetric body obtained by rotating a triangle having a base extending along the shank around the shank as the symmetric rotation axis. The double cone stylus allows the shape of an inner wall surface of a measurement object with the inner wall surface retracted from an upper reference plane to be measured from above.
