PROBLEM TO BE SOLVED: To provide a ball screw module capable of achieving high efficiency and high accuracy and forming an endless circulation route. SOLUTION: A screw and a nut constitute a first rotation track arranged in a first spiral direction. A circulating device is connected with the first rotation track and has the circulating route. The circulating route includes an intermediate route, connecting routes at both ends of the intermediate route, and at least one guiding groove. The guiding groove guides a ball connector so that it rotates in a second spiral direction along the connecting route, wherein the second spiral direction is opposite to the first spiral direction. The guiding groove guides the ball connector so that it rotates in a third spiral direction along the intermediate route, wherein the third spiral direction is the same as the first spiral direction.
