PROBLEM TO BE SOLVED: To provide an image of high resolution in a digital camera system of an interchangeable lens system. SOLUTION: An imaging apparatus has a solid-state imaging device provided with a photoelectric conversion device 201 converting incident light into an electric signal in accordance with a light volume, a micro lens 209 arranged on an incident face, an optical waveguide 203 disposed between the photoelectric conversion device and the micro lens and an interlayer insulating layer 208 disposed at a periphery of the waveguide 203. When a distance from an exit pupil of an imaging optical system to the photoelectric conversion device is set to be L, a distance from a center of an image sensor to a position of the solid-state imaging device on the image sensor to be H, height from the photoelectric conversion device to an apex of the micro lens to be D, an interval of a plurality of the solid-state imaging devices in the image sensor to be P, a refractive index of the optical waveguide to be N<SB>H</SB>, and a refractive index of the interlayer insulating layer to be N<SB>L</SB>, the solid-state imaging device positioned in the distance H satisfies a formula (1). However, 0<a<1. COPYRIGHT: (C)2006,JPO&NCIPI |
