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 1 is provided with a needle tube 2 of 26-33 G having a needle tip, a hub 3 that holds the needle tube 2, and an adjustment unit 4 provided around the needle tube 2 and having a needle-protruding surface 4b through which the needle tip of the needle tube 2 protrudes. And, the needle-protruding surface 4b of the adjustment unit 4 is formed such that the distance S from the circumferential edge to the circumferential surface of the needle tube 2 is in the range of 0.3-1.4 mm.
