Provided is an imaging apparatus, including: an imaging optical system including a plurality of lenses; and an image plane which is disposed on an image side of the imaging optical system and is curved so that a concave surface thereof faces an object side of the imaging optical system. The imaging optical system includes an aperture stop. In the imaging optical system, a lens closer to the object side than the aperture stop and a lens closer to the image side than the aperture stop have different positive powers. A focal length of the imaging optical system is substantially equal to a distance from an exit pupil of the imaging optical system to the image plane. A radius of curvature of the image plane is substantially equal to the focal length of the imaging optical system.
