Abstract
A solid-state imaging element of the present disclosure includes: a pixel array in which a plurality of unit pixels is arranged in a matrix shape, the plurality of unit pixels each including a photoelectric conversion unit; and an analog-to-digital conversion unit that converts an analog pixel signal into a digital signal, the analog pixel signal being output from each of the plurality of unit pixels of the pixel array. Then, the analog-to-digital conversion unit includes a comparator that includes a differential input unit and an active load of the differential input unit, the differential input unit using, as an input, a prescribed reference signal and the analog pixel signal. At least one transistor that configures the active load includes a plurality of control terminals that controls current. The plurality of control terminals is electrically connected in common.
