Summary:PROBLEM TO BE SOLVED: To favorably and accurately administer a liquid medicine by applying a liquid medicine administration apparatus in intracorporeally administering insulin.SOLUTION: A motor shaft 33 of a motor 32 is coaxially arranged with a piston 21, so that a force to be added to a bearing part 37 by the rotation of the motor shaft 33 and force to be added to the piston 21 by the force are applied in the same direction. Thus, the loss of thrust of the piston 21 is eliminated. Then, the piston 21 is moved by sliding at a stable stroke distance inside an internal space 22A of a cylinder part 22.
