Abstract
A scale is used in a displacement detection apparatus () which detects a position of an object, the scale includes a pattern periodically formed in a measurement direction (an X direction), and the pattern is configured so as to change a physical property in a direction (a Y direction) perpendicular to the measurement direction without changing phase information in the measurement direction when a detector reading the pattern moves relative to the pattern in the direction perpendicular to the measurement direction.
