A signal transfer circuit appropriate for use in realizing both high circuit stability and high current driving ability is disclosed. Signal transfer circuit A has current transfer circuit 3 that transfers a signal current via first reference current I1. In one embodiment, current transfer circuit 3 has current transcription circuit 30 that transcribes signal current Is to first current portion I1-1 of first reference current I1, and output current path 32 that transfers the first current portion I1-1. In one embodiment, current transfer circuit 30 has first current branching circuit 300 and second current branching circuit 302.
