Claim:
1. A D/A conversion circuit comprising: a plurality of resistors that are connected in series to each other; and a plurality of switches that are respectively connected to the plurality of resistors, the plurality of resistors and the plurality of switches being formed on a semiconductor substrate, wherein each of the plurality of resistors is configured using a resistive element and a plurality of contacts that are provided to the resistive element, wherein, when the semiconductor substrate is viewed from above, the plurality of switches are arranged side by side along a first direction, distances in the first direction between the plurality of contacts are equal to each other, and lengths in a second direction that is perpendicular to the first direction, of the plurality of resistors are unequal to each other, and wherein both ends of each of the plurality of resistors are to be the contact that is connected to an electrode of one switch of the two switches which are arranged adjacent to each other, and the contact that is connected to an electrode of the other switch.
