Zusammenfassung:A luer needle unit and an injector effectively prevent a user's fingers from being hurt when a disposable needle (1) is separated from the luer needle (2) after the use, while realizing simple and positive attachment of the luer needle (2) to a supporting cap (4). Guide protrusions and guide recesses are provided between the luer needle (2) and the supporting cap (4) to prevent the rotation thereof. Guiding projecting portions are formed in the supporting cap (4) to guide a needle part (3) of the luer needle (2) in the axial direction.
