A D/A converter has a plurality of current sources (IS1, IS2, IS3-1 to IS3-63) including transistors and selects, according to a given digital signal, paths of the currents output from the current sources (IS1, IS2, IS3-1 to IS3-63), thereby converting the digital signal to an analog signal. In the D/A converter, a forward body bias voltage is applied to the back gate terminals of the transistors constituting each of the current sources (IS1, IS2, IS3-1 to IS3-63).
