An injection needle is provided that allows design of the size of a needle base without being limited by the size of a syringe connecting part. As a hub, a needle base that is formed to have a through hole into which a needle tube is inserted, and a tubular housing where both ends in the axial direction are opened and the needle base is fitted and stored inside of one end, are formed as separate injection molded parts, thereby allowing the needle base to be largely designed. A needle tube shield part is in a box-lid shape, and the back side of a ceiling part thereof is provided with a tubular guiding part. An edge surface thereof abuts on the needle base, and a side part annularly holds and abuts on the housing. Accordingly, the needle base does not move upon receiving the pressure of a drug solution.
