Zusammenfassung:Provided is a semiconductor integrated circuit including a pad Pd1 provided on one end side of a resistive element R1 externally provided, a pad Pd5 provided on a different end side of the resistive element R1; an operation amplifier A1, a signal line L11 wired between an output terminal of the operation amplifier A1 and the pad Pd1, a signal line L21 wired between an inverting input terminal of the operation amplifier A1 and the pad Pd5, a ESD protection element r11 provided to the signal line L11, and a signal line L31, through which a voltage signal of the pad Pd1 is transmitted. The signal line L31 is connected to the pad Pd1.
