A solid-state imaging element (1) includes a pixel circuit (20) in which a first transistor (26) that amplifies a pixel signal is arranged, the pixel signal being generated by a photoelectric converter performing photoelectric conversion on light that has entered a pixel. The pixel circuit (20) includes a second transistor (27) into which a reference signal is input from a reference signal generator, and a third transistor (28) that outputs bias current to the first transistor (26) and the second transistor (27).
