A semiconductor circuit device includes an oscillation circuit, an output circuit that outputs a signal output from the oscillation circuit, a temperature sensing element, a characteristic adjustment circuit that adjusts characteristics of the oscillation circuit on the basis of a signal output from the temperature sensing element, a first wiring via which power is supplied to the output circuit, and a second wiring via which a reference voltage is supplied to the output circuit in which at least one of the first wiring and the second wiring overlaps the temperature sensing element in a plan view.
