摘要： An imaging device includes an imaging element, and an image capturing optical system configured to generate an image of an object on the imaging element. The image capturing optical system has a gradient decreasing region in which a change of a gradient of an image magnification rate with respect to an angle of view of the image generated on the imaging element decreases as a concerned position deviates farther away from an optical axis of the image capturing optical system, and a gradient increasing region in which the change of the gradient of the image magnification rate with respect to the angle of view of the image generated on the imaging element increases as the concerned position deviates farther away from the optical axis of the image capturing optical system.
