PROBLEM TO BE SOLVED: To guarantee a safety use without damaging a structure around a point of the injection needle carelessly when the needle is used by dint of preventing the sharp point from touching a periphery by bending the point of the injection needle toward a direction of a central axis. SOLUTION: An injection needle 1 is made by devising, bending of a point of the injection needle and a point 10 of the needle is bent toward a direction of central axis of the injection needle 1. Changing quantity of the point 10 which is caused by bending is not restricted especially if the quantity does not prevent a flow of liquid, i.e., medical liquid and a humor which pass a flow path 11 of the injection needle 1 and is not obstruct puncture of the injection needle 1, but over one forth and below two third of an external diameter of the injection needle 1 is desirable. Thereby, a user can inject safely and securely without damaging a peripheral structure of the point of the injection needle 1 carelessly even if a minor trouble is caused in a use of the needle. |
