This invention provides a positioning apparatus which can safely stop a movable body irrespective of its driving status. This invention relates to a positioning apparatus which positions a movable body (4) of an exposure apparatus and includes a driver (2) which drives the movable body (4), a power source (3) which supplies power to the driver (2), and a controller (1). The controller (1) stops the power supply from the power source (3) to the driver (2) after the elapse of a time period, which is determined in accordance with the driving status of the movable body (4) driven by the driver (2), in response to a stop instruction signal (11) which instructs to stop the driving of the movable body (4).
