PROBLEM TO BE SOLVED: To provide a liquid discharge nozzle capable of improving accuracy in ejection of liquid.SOLUTION: A liquid discharge nozzle 1 has a double pipe structure including an inner pipe 10 and an outer pipe 20. A downstream end 12 of the inner pipe is protruded out of the outer pipe 20. When the liquid discharge nozzle 1 is fixed to a syringe 60, an upstream end 11 of the inner pipe is inserted into a tip end 61 of the syringe 60. This prevents adverse effect on accuracy in ejection of liquid even when air remains within the liquid discharge nozzle 1. |
