摘要：
The purpose of the present invention is to provide a method for producing a puncture needle that causes less pain upon use, such as at the time of piercing. This is solved by a puncture needle producing method comprising a step of processing a pipe shaped metal base material, which has on one end thereof a ground surface made by machining, with a plasma generated in an atmosphere filled with a gas mixture including a principal gas and a reactive gas as main components.
