Claim 14:
15. An electronic apparatus, comprising:
a solid-state imaging device that includes:
a first pixel separation region that separates a plurality of unit pixels, wherein each unit pixel of the plurality of unit pixels includes at least two subpixels;
a second pixel separation region that separates each unit pixel of the plurality of unit pixels into the at least two subpixels;
an overflow region configured to control a plurality of signal charges in each subpixel of the at least two subpixels to overflow to at least one adjacent subpixel of the at least two subpixels, wherein the overflow region is between a first subpixel of the at least two subpixels and a second subpixel of the at least two subpixels;
a first P-type region in a depth direction inside the first pixel separation region;
a second P-type region in the depth direction around the second pixel separation region; and
an N-type region between the first P-type region and the second P-type region, wherein
the first pixel separation region, the overflow region, and the second pixel separation region are included in a cross section in which a region of a unit pixel that is not separated by the second pixel separation region is cut along an incident direction of light, and
the overflow region has at least one of:
a third P-type region whose impurity concentration is lower than an average impurity concentration of the first P-type region,
a fourth P-type region whose impurity concentration is lower than an average impurity concentration of the second P-type region, or
a fifth N-type region between the third P-type region and the fourth P-type region.
