In a load driving circuit, a detection current Is (=Io/N), 1/N of a driving current Io, flows in a detection resistor, where N indicates a shunt ratio between a current (=driving current Io) that flows in an output source (S1) and a current (=detection current Is) that flows in a detection source (S2). The shunt ratio is determined by a cell ratio between the output source (S1) and the detection source (S2).
