PROBLEM TO BE SOLVED: To provide a nail increased in pull-out resistance, in regard to a nail provided with a large number of slip-off stop protrusions at a body part between a nail head and a nail tip in the axis direction of the body part so as to project in an orthogonal direction to the axis of the body part. SOLUTION: The nail is provided with a large number of first slip-off stop protrusions 7 at the body part in the axis X direction of the body part so as to project in the orthogonal direction to the axis X of the body part, and the second slip-off stop protrusions 8 projected longer in the orthogonal direction to the axis X of the body part than the first slip-off stop protrusions 7 and provided at a driving part of the body part 4 into a mounted member 3 partially in the axis X direction of the body part.
