摘要:
An injection needle includes a needle tube, a first ground facet formed on a distal end of the needle tube, and at least two ground facets subsequently formed on the needle tube to provide a needle point. The needle point of the injection needle is not located on a central plane that perpendicularly crosses the first ground facet and includes a central axis of the needle tube. A length (A) in a central axis direction of an edge surface including the first ground facet and the at least two ground facets is in the range of 0.6 to 2.2 mm, an outside diameter (L) of the needle tube is in the range of 0.18 to 0.6 mm, and a value of the outside diameter (L) of the needle tube/the length (A) is in the range of 0.265 to 0.325.
