A circuit apparatus is a circuit apparatus used for a physical quantity measuring apparatus, including a detection circuit that performs physical quantity detection processing based on a detection signal from a physical quantity transducer and a processing circuit that performs processing based on an output signal of the detection circuit. The processing circuit obtains index information of floor noise generated in the detection circuit based on the output signal and performs abnormality detection of the physical quantity measuring apparatus based on the index information.
