Abstract: A solid-state imaging device includes: a first substrate having first photoelectric converters; a second substrate having second photoelectric converters and laminated on the first substrate; micro lenses disposed on an opposite face facing an imaging lens among faces of the second substrate and which forms an image of light passing through the imaging lens; and a light shielding layer disposed between the first and second photoelectric converters. The light shielding layer includes: a selection portion provided with an opening portion which selectively allows passage of only light passing through a partial region of a pupil region in an exit pupil of the imaging lens among light passing through the micro lens and transmitted through the second photoelectric converter; and a light shielding portion which shields an entire light passing through the micro lens and transmitted through the second photoelectric converter.
