Abstract

A puncture needle is constituted of a resin material. The puncture needle comprises: an elongated main body having a sharp needlepoint at a distal end thereof; and at least three cutting parts provided so as to project from the elongated main body to a direction perpendicular to a central axis of the elongated main body, extending along the central axis, and arranged around the central axis. Adjacent cutting parts in the three cutting parts are arranged so as to shift to each other in a direction of the central axis, so that the adjacent cutting parts make an incision on a biological surface in a time difference. Further, a height of a distal portion of each cutting part from the central axis is gradually decreased toward a distal direction.
