An intradermal injection needle is an intradermal injection needle assembly to be used by piercing the intradermal injection needle into the skin of a living body. The intradermal injection needle has a hollow needle having a blade edge pierceable into the skin and a discharge port of an administration product; and a hub holding the hollow needle. The hollow needle has an outer diameter of 0.15 to 0.20 mm. The discharge port has a length of 0.10 to 0.80 mm in an axial direction of the hollow needle. When the intradermal injection needle is pierced into the skin of the living body, the discharge port thereof is entirely subcutaneously pierceable within a range of 0.20 to 1.00 mm.
