A shape measuring apparatus includes a stage, a light projecting portion, a light receiving portion, and a rotation unit. The rotation unit is attached to an end of the stage. The rotation unit rotates the measurement subject about a rotation axis that vertically intersects while holding the measurement subject. In a state where the measurement subject is at a predetermined rotation angular position, the pattern light is emitted from the light projecting portion to the measurement subject a plurality of times while being phase-shifted. At this time, the light receiving portion captures an image of the measurement subject. Three-dimensional shape data is generated on the basis of a plurality of pieces of image data obtained by imaging.
