PROBLEM TO BE SOLVED: To provide a single-hole punch capable which forms a plurality of arbitrary holes at desired intervals by improving a well-known one. SOLUTION: This single-hole punch is provided with a probe of a protrusion shape in a position vertically under a press blade and protruding from a rear cover. When a hole is to be formed in paper, the paper to be punched is overlapped on a base paper having a hole, and a bottom plate and the rear cover are inserted between them. When sliding the punch on the base paper fits the probe into the hole, a pushing lever is pushed down in that state, and a hole is formed in an accurate position of the paper.
