Abstract
A needle tip of a needle tube stuck in the skin is caused to be reliably positioned in the skin upper layer part and the injected drug is caused not to leak to the outside of the body. An injection needle is provided with a needle tube having a needle tip, a hub that holds the needle tube and an adjustment unit provided around the needle tube and having a needle-protruding surface through which the needle tip of the needle tube protrudes. The needle-protruding surface of the adjustment unit is formed such that the distance S from the circumferential edge to the circumferential surface of the needle tube is in the range of 0.3-1.4 mm.
