Claim Text:
1. A solid-state imaging apparatus, comprising a plurality of pixels each comprising: a photoelectric conversion unit configured to generate a signal charge by photoelectric conversion of incident light; a charge accumulation unit configured to accumulate the signal charge transferred from the photoelectric conversion unit; a transistor configured to transfer the signal charge from the photoelectric conversion unit to the charge accumulation unit, the transistor comprising a control electrode; a floating diffusion portion configured to receive the signal charge transferred from the charge accumulation unit; a waveguide configured to guide the incident light into the photoelectric conversion unit; and a light-shielding portion covering at least the charge accumulation unit and having an opening that allows the light output from the waveguide to pass therethrough, wherein the waveguide comprises an incident portion which the light enters and an output portion from which the light is output, the light-shielding portion comprises a first portion that covers the control electrode of the transistor and a second portion that covers a part of the photoelectric conversion unit, the output portion and the photoelectric conversion unit are arranged with an interval therebetween, the interval between the output portion and the photoelectric conversion unit is larger than an interval between a lower end of the second portion of the light-shielding portion and the photoelectric conversion unit, and the interval between the output portion and the photoelectric conversion unit is smaller than an interval between an upper end of the second portion of the light-shielding portion and the photoelectric conversion unit.
