A transfer circuit that transmits a signal includes an electrical signal sending section that sends a sending signal, a current to light converting section that converts the sending signal to an optical signal, an optical signal transmitting section that transmits the optical signal, a photo-electric converting circuit that converts the optical signal to an electrical signal, and an electrical signal receiving section that detects a data value of the electrical signal. The photo-electric converting circuit includes a level measuring section that compares the intensity of the electrical signal and a predetermined reference level to detect a data value of the electrical signal, and a measurement controlling section that controls the reference level. The electrical signal receiving section includes a receiving circuit that detects a data value of the electrical signal, and a timing controlling section that controls latch timing at which the receiving circuit detects the data value.
