Abstract
A needle tube having a needle tip for puncturing skin; a needle hub; and a fluid-draining portion for enabling draining of a medicine. The needle hub includes: a retention part (first member) for retaining the needle tube; an insertion part into which the output portion of a syringe is inserted; and a flange-like skin contact portion that is disposed in a manner so as to cover an area surrounding the needle tube and makes contact with and/or faces the skin when a living body is punctured with the needle tube. The fluid-draining portion is disposed in the skin contact portion of the needle hub and enables a user to drain the medicine that has spilled when removing air and is held in the skin contact portion.
