Abstract
A solid-state imaging apparatus, comprising a plurality of pixels arranged on a substrate, and element isolation regions formed between the plurality of pixels on the substrate, wherein the plurality of pixels include a first pixel including a first color filter for passing light having a first wavelength, a second pixel including a second color filter for passing light having a second wavelength shorter than the first wavelength, and a pixel for focus detection into which light longer than at least the second wavelength enters, and of the element isolation regions, a first region between the pixel for focus detection and the first pixel has a potential barrier against a signal charge, which is higher than that of a second region between the first pixel and the second pixel.
