A hair implanter is equipped with a tube in which a shaft is disposed movable in an axial direction thereof, a tapered hollow needle extending from a tip end of the tube, and slits extending from a tip of the needle in an axial direction thereof to divide a body of the needle into a plurality of needle strips. The needle strips are so shaped that when the shaft is pushed, it contacts inner surfaces of the needle strips, and when the shaft is further advanced in sliding contact with the inner surfaces of the needle strips, the needle strips will elastically bend radially outwardly. Each of the slits extends toward the base end of the tube across a point at which the shaft contacts the inner surfaces of the needle strips. This achieves smooth opening of the tip of the needle with a small degree of force pushing the shaft.
