PROBLEM TO BE SOLVED: To restrict the entire length of an infusion pump and frame when the infusion pump is attached to a pole via the frame.SOLUTION: A recessed part 15 for arranging a frame is formed on the bottom part of a pump body 11, and the depth of the recessed part 15 (the depths of front and rear legs 14a, 14b with respect to their lowermost ends) is made greater than the height of the portion (frame body 20) of the frame 2 arranged on the recessed part 15. Providing the pump body 11 with such a recessed part 15 for frame arrangement, prevents the frame 2 from jutting out from the lowermost ends of the front and rear legs 14a, 14b of the frame 2 (frame body 20) while the infusion pump 1 being attached to the frame 2. Thus, the entire height of the infusion pump 1 and frame 2 with the pump 1 attached thereto can be restricted to the height of the infusion pump 1 itself (the height of the infusion pump 1 from the respect lowermost ends of the front and rear legs 14a, 14b to their tops).
