A drive circuit that outputs low-voltage differential signals to an external load circuit, including: first and second nodes to which the external load circuit is connected; a first series circuit including first and second switching elements, connected in series using the first node as a common node; a second series circuit including third and fourth switching elements, connected in series using the second node as a common node; and a first current source that outputs a predetermined current to the first and second series circuits, in which a back gate of a transistor of a first conductivity type included in at least one of the first and third switching elements or the first current source is forward-biased.
