  • Publication number: 20160303332
    Abstract: An injection needle 1 made of an alloy containing cobalt and molybdenum is manufactured as follows. First, a lancet cut is carried out to a pipe-like metallic material composed of the alloy containing cobalt and molybdenum to form a blade tip 3 and a blade part 5. Then, a distal end part 1A including the blade tip 3 is mechanically polished, and thereafter, the distal end part 1A is immersed in an electrolytic solution and electrolytically polished. Thus, burrs at the blade tip 3 or the like generated during mechanical polishing are removed. Since the injection needle 1 is composed of the alloy containing cobalt and molybdenum, compared to a conventional injection needle made of stainless steel, an injection needle in which the surface roughness of an inner peripheral surface of the injection needle is low and smooth can be provided.
