An imaging apparatus includes an imaging optical system configured to form an image of an object, an imaging element configured to pick up the image of the object, and optical waveguides configured to guide light from the imaging optical system to the imaging element. A refractive index of a medium adjacent to an incident surface of each of the optical waveguides is higher than that of a center part of the optical waveguide. The following condition is satisfied: 0 < α < θp < β where α represents an angle formed by an axis of the optical waveguide and an optical axis of the imaging optical system, θp represents an angle formed by a principal ray of a light beam incident on the optical waveguide and the optical axis, and β represents an angle formed by a surface normal to a center of the incident surface and the optical axis. |
