PROBLEM TO BE SOLVED: To provide a loading device that allows smooth inflow of liquid from introduction holes into introduction parts even when insertion positions of the introduction parts are deviated from the axial center of a flow passage of a supply part due to a tolerance or the like while preventing gas from being mixed into the introduction parts when the liquid storage body is replaced, and also to provide a liquid feeder, and a liquid jet device. SOLUTION: A pair of the introduction holes 61, which is opened on the outer peripheral face other than a conical tapered-part 23a at the tip part, is formed to each of a plurality of supply needles 23 protrudingly provided to a holder 20. A pair of the introduction holes 61 has an opening 61a opened on the outer peripheral face of the supply needle 23 at an inclination angleθtaken in the circumferential direction of the supply needle 23 to a virtual reference line S passing through the axial center O of the supply needle 23 and parallel to an arrangement direction Z of a plurality of the supply needles 23 in a range of the inclination angleθ(in a prescribed range from about 30 to 60 degrees) relative to a groove 53a formed on an inner face of the flow passage 53.
