PROBLEM TO BE SOLVED: To secure pressing force and a puncturing speed required when a needle tube punctures the skin, and to reliably position a needle tip of the needle tube on the upper layer of the skin.SOLUTION: The injection needle assembly 2 includes the needle tube 5 provided with a needle tip 8 capable of puncturing a living body, a hub 6 for holding the needle tube 5, a stabilizing part 13, and a puncturing speed securing member 7. The stabilizing part 13 is disposed to cover the periphery of the needle tube 5 and has an end face 13a to be in contact with the skin when the needle tube 5 punctures the living body. Then, the puncturing speed securing member 7 is provided in the hub 6, is brought into contact with the skin before the needle tip 8 of the needle tube when the needle tube 5 punctures the living body, and secures the speed and the pressing force when the needle tube 5 punctures the living body. |
