Abstract
A luer needle unit and an injector effectively prevent a user's fingers from being hurt when a disposable needle is separated from the luer needle after use, while realizing simple and positive attachment of the luer needle to a supporting cap. Guide protrusions and guide recesses are provided between the luer needle and the supporting cap to prevent the rotation thereof. Guiding projecting portions are formed in the supporting cap to guide a needle part of the luer needle in the axial direction.
