Imaging device having an effective pixel region, an optical black region and a dummy region each with pixels including a photoelectric converter

An imaging device comprising:

• an effective pixel region in which a plurality of pixels, each including a photoelectric converter and an optical waveguide arranged above the photoelectric converter, are arranged;
• an optical black region covered with a light-shielding film, in which a plurality of pixels, each including a photoelectric converter and an optical waveguide arranged above the photoelectric converter and under the light-shielding film, are arranged;
• a first connecting portion, which is made of a material having a same characteristic as a characteristic of the optical waveguide, provided so as to connect the optical waveguides of the plurality of pixels arranged in the effective pixel region to each other;
• and
• a second connecting portion, which is made of the material having the same characteristic as the characteristic of the optical waveguide, provided so as to connect the optical waveguides of the plurality of pixels arranged in the optical black region to each other,
• wherein the first connecting portion and the second connecting portion are arranged so as to be spaced apart from each other.
