摘要： A solid-state imaging device includes a first chip and a second chip. The first chip includes a pixel array in which a plurality of photodiodes corresponding to each pixel of a captured image is disposed in a two-dimensional array shape. Each photodiode generates a pixel signal corresponding to a signal charge generated by the photoelectric conversion of the photodiode. The first chip is stacked on the second chip that includes a memory storing the pixel signals generated from the first chip, where the memory is located outside a projection region formed by projecting the pixel array and in a thickness direction of the first chip.
