Solid-state imaging device and imaging system

A solid-state imaging device comprising:

• a plurality of pixels, each of the plurality of pixels including a photoelectric converter that generates charges by photoelectric conversion and a charge holding portion that holds charges transferred from the photoelectric converter,
• wherein the photoelectric converter includes a first semiconductor region of a first conductivity type provided in a surface portion of a semiconductor substrate, a second semiconductor region of a second conductivity type provided under the first semiconductor region and configured to accumulate generated charges, a third semiconductor region of the first conductivity type provided under the second semiconductor region, and a fifth semiconductor region of the second conductivity type provided in a depth between the first semiconductor region and the third semiconductor region,
• wherein the second semiconductor region is provided in a first region that does not overlap with the third semiconductor region in a plan view and a second region that overlaps with the third semiconductor region in the plan view, and
• wherein the fifth semiconductor region is provided in a same region as a region in which the third semiconductor region is provided in the plan view.
