Provided are a solid-state imaging device, an imaging device, and a signal reading method, which may reduce the degradation of signal quality, suppress an increase in a chip area, and suppress an increase in current consumption. The solid-state imaging device includes a plurality of pixels classified as first to nth (where n is an integer greater than or equal to 2) pixels, wherein each of the plurality of pixels includes a photoelectric conversion element arranged on a first substrate, an amplification circuit configured to output an amplified signal by amplifying a signal generated by the photoelectric conversion element, and a signal accumulation circuit arranged on a second substrate and configured to accumulate the amplified signal output from the amplification circuit, and a control unit configured to control a drive current to be exclusively supplied to the amplification circuit of each of the first to nth pixels.
