An electronic element and a circuit device is provided that varies a physical quantity of a passive element in a wide range including when the physical quantity is zero. A variable capacitance element includes a switch and an element that configures a capacitor. The switch has a source electrode, a drain electrode, a channel forming film that overlaps at least a part of the source and drain electrodes, a gate insulating film that overlaps the channel forming film, and a gate electrode on the gate insulating film. The element has a terminal electrode electrically connected to the source electrode, and a terminal electrode that configures a capacitor between the terminal electrode and a part of the drain electrode by sandwiching a dielectric layer therebetween or being in contact with the dielectric layer. The dielectric layer and the gate insulating film are the same insulating film.
