Physical Quantity Measurement Device, Electronic Apparatus, And Vehicle

A physical quantity measurement device comprising:

• a sensor having a drive electrode and a detection electrode, and provided with a coupling capacitance formed between the drive electrode and the detection electrode;
• and
• a circuit device having a drive circuit adapted to supply a drive signal to the drive electrode, a detection circuit adapted to detect physical quantity information corresponding to a physical quantity based on a detection signal from the detection electrode, and a fault diagnosis circuit,
• wherein the fault diagnosis circuit has an electrostatic leakage component extraction circuit adapted to extract an electrostatic leakage component due to the coupling capacitance from one of the detection signal and an amplified signal of the detection signal, and performs a fault diagnosis based on the electrostatic leakage component extracted.
