PROBLEM TO BE SOLVED: To provide a syringe needle in which insertion resistance is reduced, the generation of a fore pushing a needle back to the outside after insertion is suppressed and coring is prevented and to further provide a syringe needle in which a flow rate of a certain degree is secured in the inflow/outflow of chemicals or the like and inflow-outflow resistance is reduced. SOLUTION: In the syringe needle having a hard hollow needle and a needle hub on the base end of the hollow needle, a flat face is provided on the top end of the hollow needle and a slope is provided from the flat face toward the needle hub. |
