In a driver circuit including transistors each having an emitter follower configuration and a pair of differential transistors with emitter outputs of the transistors of the emitter follower configuration as inputs, end terminals of the pair of differential transistors are connected to individual bonding pads, and the respective bonding pads and voltage sources are individually connected by wires that function as inductors. Thereby, even in the case where the lengths of the wires of output terminals change according to packaging, outputs can be matched by determining the wire lengths of the wires suitably.
