A digital/analog converter including four D/A conversion. The D/A convertor comprises four D/A conversion parts (DA1) to (DA4). On a single semiconductor chip the D/A convertion parts (DA1) to (DA4) are arranged so that the D/A conversion parts (DA1) and (DA3) are symmetric with respect to a first center line (L1), the first and fourth D/A conversion parts (DA1) and (DA4) are arranged symmetric with respect to a second center line (L2) which crosses the first center line (L1) at right angles and the second and third D/A conversion parts are arranged symmetric with respect to the second center line. Although the locations of the resistances of each of the conversion parts produces errors, these cancel each other out due to their arrangement.
