Abstract: A solid-state image pickup device includes: a pixel portion in which a plurality of pixels are arrayed in matrix; and an Analog-Digital converter. The Analog-Digital converter converts pixel signals, which are generated in the pixel portion, from analog signals into digital signals. The Analog-Digital converter includes: a comparator; and a counter. The comparator compares the analog signals, each of which corresponds to each of the plurality of pixels, with a reference signal. The comparator includes: a first differential transistor to which the reference signal is input; a second differential transistor to which the analog signals are input; a first load transistor; a second load transistor; and a current source transistor. A fluctuation of a voltage between a gate and a source of the first differential transistor is suppressed. This fluctuation follows a voltage fluctuation of a node connected commonly to the second differential transistor and the second load transistor.
