Provided is a liquid supply tool capable of reliably forming an air hole, and capable of smoothly supplying a liquid. The tool is provided, in an outer cylinder (12), with a liquid retaining unit (20) for retaining a liquid, and a liquid supply body (30) which projects from the liquid retaining unit (20) toward a tip end opening (18a) of the outer cylinder (12) and is capable of guiding the liquid within the liquid retaining unit (20) to the outside through the tip end opening (18a). The liquid supply body (30) comprises a core (32) for guiding the liquid, and an outer casing (34) provided around the core (32). The core (32) and the outer casing (34) are integrally formed, the outer casing (34) surrounds the external circumference of the core (32) from the tip end portion of the core (32) to the liquid retaining unit (20), and at least one air hole (34a) is formed within the cylindrical wall of the outer casing (34) so that the air hole (34a) extends from the tip end side of the core (32) to the inside of the liquid retaining unit (20) by penetrating in the axial direction. |
