Claim:
1. A shape measuring apparatus configured to measure a shape of a subject, the apparatus comprising: a probe including an irradiating optical system configured to irradiate the subject with light and an imaging element configured to detect light with which the subject is irradiated and which is reflected by the subject; a rotator configured to rotate the probe around the subject with the probe distanced from a rotation axis of the rotator; a holder disposed at a distance from a rotation axis of the rotator, the holder holding the probe and changing an attitude of the probe relative to the subject in accordance with the rotation of the probe; a calculator configured to calculate shape information of the subject using a signal detected from the imaging element using the probe; and a corrector configured to correct the shape information of the subject based on a deformation of the holder.
