A punch capable of punching and embossing a rectangular corner of a sheet member at two directions of a jig is disclosed. The punch includes a jig having two punching regions symmetrically disposed on the basis of a punching center so that a main pattern hole is formed in one punching region and a convex embossment is formed on the other punching region; a base for fixing the jig and giving a supply surface so that a rectangular corner of a sheet member to be punched is supplied to the punching region; a punching member having a punch pin and a concave embossment corresponding to the pattern hole and the convex embossment, and punching and/or embossing the rectangular corner of the supplied sheet member with vertically moving against the jig; and an elastic body interposed between the punching member and the jig to elastically bias the punching member upward.
