Provided are a low-cost ball screw device having a low-cost deflector, wherein the deflector is formable by simple machining, is easy to handle after being machined, and thus is easy to store and mount to another component. A ball screw device includes a screw shaft, a nut, rolling elements, and deflectors. Mounting holes each have a pair of circumferentially facing surfaces that face toward each other in the circumferential direction of the nut and parallel to each other. When a plane passing through the center point of an opening in one end of a second circulation path in each of the pair of deflectors and the axis of the nut is defined as a reference plane, an intersection line between an imaginary perpendicular plane perpendicular to the axis and the pair of circumferentially facing surfaces has an angle with respect to the reference plane.
