A current mirror circuit includes a first transistor having a source node connected to a reference potential, a second transistor having a source node coupled to a drain node of the first transistor and a gate node connected to a first predetermined potential, an inverted amplification circuit having a non-inverted input node coupled to a drain node of the second transistor, an inverted input node coupled to a second predetermined potential, and an output node coupled to a gate node of the first transistor, a third transistor having a gate node connected to a potential substantially equal to a potential of the gate node of the first transistor, and a fourth transistor having a gate node connected to a potential substantially equal to a potential of the gate node of the second transistor.
