摘要：
A distance measurement accuracy is improved. A solid-state imaging device according to an embodiment includes a pixel array part (101) in which a plurality of pixels (20-1) is arranged in a matrix, in which each of the pixels includes a plurality of photoelectric conversion units (211,212) that each photoelectrically converts incident light to generate a charge, a floating diffusion region (27) that accumulates the charge, a plurality of transfer circuits (23, 24, 25) that transfer the charge generated in each of the plurality of photoelectric conversion units to the floating diffusion region, and a first transistor (28) that causes a pixel signal of a voltage value corresponding to a charge amount of the charge accumulated in the floating diffusion region to appear in a signal line.
