Abstract

A medical puncture needle includes a rod-shaped main body portion; and a blade surface formed at a distal end portion of the main body portion. The blade surface includes a first blade surface portion and a second blade surface portion that intersect to form a blade edge. A needle tip is formed at a location at which a distal end of the blade edge intersects a first ridge line at an outer edge of the first blade surface and a second ridge line at an outer edge of the second blade surface. At least one of the blade surface portions is planar, and, in a central axis direction of the main body portion, said at least one blade surface portion extends to a location proximal of a middle position of a blade surface region in which the blade surface is formed.
