A drug transferring needle of the present invention includes a needle base portion, a first needle portion which has therein an air passage, and a second needle portion which is longer than the first needle portion and is arranged parallel to the first needle portion. In the first needle portion, a first air vent which is one end of the air passage is provided on a distal end side of the second needle portion from a second air vent which is 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 of the liquid passage 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 which connects the distal end and the base portion. In the medicine transferring needle of the present invention, a diameter of the intermediate portion is larger than a diameter of the distal end, and the diameter of the intermediate portion is smaller than a diameter of the base portion.
