PROBLEM TO BE SOLVED: To convert a digital input into an analog output without an effect of nonlinearity characteristics of a switch on an output signal. SOLUTION: This digital-to-analog converter comprises analog output elements 104A, 104B, 104C, 104D, 104E and 304 which selectively generate partial analog signals in response to a digital input, adders 108, 208, 208A and 208B which are connected to the analog output elements 104A, 104B, 104C, 104D, 104E and 304 and generate analog outputs by combining the partial analog signals, and switches 106, 306 which are connected between the analog output elements 104A, 104B, 104C, 104D, 104E and 304 and the adders 108, 208, 208A and 208B and adjust transmissions of the above partial analog signals from the analog output elements 104A, 104B, 104C, 104D, 104E and 304 to the adders 108, 208, 208A and 208B.
