To provide a milker for a mouse or a rat which is simply introduced, and improves the workability.

The one-handed milker 1 for the mouse or the rat includes: an eppendorf tube 2; a plug 3; a milking pipe 4; an air release pipe 5; and a negative pressure adjusting pipe 6. The milking pipe 4 is an L-shaped pipe, inserted to the plug at one end, and attached to a nipple at the other end. The air release pipe 5 is also an L-shaped pipe, inserted to the plug at one end, and connected to a suction pump. The negative pressure adjusting pipe 6 is a straight pipe, inserted to the plug at one end, and extended at the other end in the axial direction in comparison with both L-shaped pipes. A worker pinches the eppendorf tube 2 in one hand, holds the milking pipe 4 with a middle finger and a thumb, attaches its end to the nipple of the mouse or the rat, opens and closes the end of the negative pressure adjusting pipe 6 with an index finger, and adjusts a suction power.
