An imaging apparatus attachable to a left side or a right side of a moving body, the imaging apparatus comprising: an image sensor that includes an imaging surface having a plurality of pixels arranged two-dimensionally and that generates image data from a subject image formed on the imaging surface, wherein the pixel distribution is uniform in the horizontal and vertical directions; and an optical system that forms the subject image included in a range of a predetermined vertical view angle and a predetermined horizontal view angle on the imaging surface, wherein an optical axis of the optical system passes through a center of the imaging surface of the image sensor and orthogonally intersects the imaging surface, wherein a number of pixels for capturing the subject image included in a unit view angle is defined as resolution, the imaging surface includes a first region for capturing a first subject image of the subject image and a second region for capturing a second subject image of the subject image different from the first region, the first region being located inside the second region; the optical system includes a set of free-form lenses (111, 112) that constitutes a lens that causes the magnification ratio of the image to be formed to vary depending on the view angle and forms the subject image on the imaging surface so as to cause resolution of the first region to be higher than resolution of the second region, wherein the imaging apparatus, when being attached to the left side or the right side of the moving body, captures images of the respective side and an oblique rear side of the moving body, characterized in that when the imaging apparatus is an imaging apparatus configured for the left side of the moving body, a position of a center of the first region is a position horizontally shifted from a center of the predetermined horizontal view angle, the second region, the first region, and the second region are arranged in order in the horizontal direction from the moving body side, and when the imaging apparatus is an imaging apparatus configured for the right side of the moving body, the position of the center of the first region is a position horizontally shifted from the center of the predetermined horizontal view angle in the direction opposite to the imaging apparatus for the left side, the second region, the first region, and the second region are arranged in order in the horizontal direction from the moving body side wherein a number of peaks of the resolution in each of the predetermined horizontal view angle and the predetermined vertical view angle is one wherein the position of the center of the first region is disposed at the position horizontally shifted from the center of the horizontal view angle toward a region for forming an image of a part of the moving body. an image sensor that includes an imaging surface having a plurality of pixels arranged two-dimensionally and that generates image data from a subject image formed on the imaging surface, wherein the pixel distribution is uniform in the horizontal and vertical directions;
