Imaging device

An imaging device, comprising:

• a photoelectric converter;
• a protection member provided on a light incident side of the photoelectric converter;
• a substrate opposed to the protection member with the photoelectric converter interposed therebetween and having a first surface on the photoelectric converter side and a second surface opposed to the first surface;
• a rewiring layer provided in a selective region of the second surface of the substrate;
• and
• a protective resin layer provided on the second surface of the substrate,
• wherein the second surface of the substrate has:
• a first external terminal coupling region exposed from the protective resin layer,
• a second external terminal coupling region exposed from the protective resin layer, and
• a stress relaxation region exposed from the protective resin layer and disposed at a position different from the first external terminal coupling region,
• wherein the stress relaxation region includes the rewiring layer, and
• wherein the stress relaxation region is disposed between the first external terminal coupling region and the second external terminal coupling region.
