Disclosed is a differential amplifier circuit that comprises: a first differential pair of a first conductivity type having an input pair connected to respective input terminals and an output pair connected to a load-element pair; a second differential pair of a second conductivity type having an input pair connected to the respective input terminals and an output pair connected to a load-element pair; a first output transistor connected between a first power supply and an output terminal and having a control terminal connected to a first output of the first differential pair; and a second output transistor connected between a second power supply and the output terminal and having a control terminal connected to a first output of the second differential pair. A current having a value that is the result of adding a current, which is the result of reflecting a current of the second output of the second differential pair by a current mirror, to a current of the first output of the first differential pair, is passed into the load element connected to the first output of the first differential pair.
