Abstract
A positioning method of a photoelectric conversion device (an imaging device) includes irradiating an optical member with light and receiving light which passes through an opening of a light shielding member and the optical member with the photoelectric conversion device. The photoelectric conversion device is moved in a direction orthogonal to an optical axis of the optical member and a first position at which the photoelectric conversion device detects a side of an opening and a second position at which the photoelectric conversion device detects another side opposing the side are acquired. A position of the photoelectric conversion device at which a center of the opening and a center position of the photoelectric conversion device are aligned based on the first position and the second position is determined. The photoelectric conversion device is fixed at the determined position.
