Abstract
A D/A conversion circuit includes a plurality of resistors connected to each other in series, a plurality of MOS transistors connected to each other so as to correspond to a plurality of contacts, and a plurality of dummy electrodes respectively disposed on sides opposite to the plurality of MOS transistors with a resistive element interposed therebetween when seen in a plan view of a semiconductor substrate. Each of the dummy electrodes is set to be in a second potential state when a gate electrode of the MOS transistor disposed on a side opposite thereto with the resistive element interposed therebetween is in a first potential state, and is set to be in a first potential state when the gate electrode of the MOS transistor is in a second potential state.
