Abstract
A solid-state imaging device according to an embodiment includes: a plurality of pixels arranged on a first face of a first semiconductor layer, each of the pixels including a photoelectric conversion element converting light entering through a second face of the first semiconductor layer on the opposite side from the first face into a signal charge, the photoelectric conversion element having a pn junction formed with a first semiconductor region formed on the first face and a second semiconductor region formed on a surface of the first semiconductor region; pixel separating regions separating the pixels from one another and formed between the pixels, each of the pixel separating regions including a second semiconductor layer covering faces in contact with the photoelectric conversion elements, and an insulating film with a lower refractive index than a refractive index of the second semiconductor layer to cover the second semiconductor layer.
