PROBLEM TO BE SOLVED: To provide a digital/analog converter which can reduce the size of an IC. SOLUTION: The digital/analog converter includes a first divided voltage generator 301 which divides the voltage of a reference power supply by a voltage distribution, a decoder 303 which outputs a selection signal decoded from an input digital signal, a first divided voltage selector 302 which selects and outputs a plurality of divided voltages of the divided voltages of the generator 301 on the basis of the selection signal from the decoder 303, a second divided voltage selector 304 which selects and outputs the plurality of the divided voltages from the selector 302 on the basis of the selection signal from the decoder 303, a second divided voltage generator 305 which divides the plurality of the divided voltages from the selector 304, a third divided voltage selector 306 which selects a predetermined voltage of the divided voltages of the generator 305 on the basis of the selection signal from the decoder 303, and a voltage output unit 307 which outputs a predetermined voltage from the selector 306.
