1. A color image sensor comprising:

  • a white light source radiating white light on an original;

    a microlens array for condensing light emitted from said white light source and reflected from the original;

    an optical waveguide array having a plurality of waveguides which transmit the condensed light which has been focused by said microlens array; and

    a photoelectric converting device which receives light transmitted through the plurality of waveguides and converts the light into electric signals,said optical waveguide array having laminated structure made up of three waveguide layers, each waveguide layer having one of three color filters which allow light to form three independent color beams that cover the complete range of colors.
