A measurement apparatus which illuminates a pattern positioned on an object plane to form an aerial image 40 on an image plane and measures a light intensity distribution of the aerial image 40 via a slit 54 on the image plane, the measurement apparatus including a stage 60 moving the slit, a light receiving element 53 mounted on the stage 60 and including at least two light receiving portions which receive the light transmitted through the slit, a storage unit which stores a relationship between an angle epsilon and a distance between a center position of the slit 54 and a position where a intensity of light that the light receiving element 53 receives is maximum, a calculation unit which obtains the angle epsilon, and a stage driving unit 80 which rotates the stage 60 so that the angle epsilon is equal to zero.
