摘要：
A drug transferring needle includes a needle base portion, a first needle portion having therein an air passage, and a second needle portion longer than the first needle portion and arranged parallel to the first needle portion. In the first needle portion, a first air vent being one end of the air passage is provided on a distal end side of the second needle portion from a second air vent being the other end of the air passage. In the second needle portion, one end of a liquid passage is connected to the inside of the needle base portion, and the other end thereof is a liquid pass opening of the second needle portion. The second needle portion has a distal end having the liquid pass opening, a base portion connected to the needle base portion, and an intermediate portion connecting the distal end and the base portion.
