Inertial force sensor

An inertial force sensor comprising:

• a detection element;
• a temperature sensor that detects an ambient temperature of the detection element;
• a bridge circuit that processes an output signal from the detection element;
• an AD converter that converts an analog signal output from the bridge circuit into a digital output signal, and outputs the digital output signal;
• a calculation circuit that performs calculation on the output signal from the AD converter;
• and
• a storage that stores correction data for correcting a variation in the digital output signal from the AD converter due to a temperature change,
• wherein the correction data includes a first calibration curve, having a first coefficient, and a second calibration curve, having a second coefficient different from the first coefficient, that are a quadratic or higher-degree curve, and
• wherein the calculation circuit calculates based on the first calibration curve when the detected ambient temperature is less than the predetermined temperature and calculates based on the second calibration curve when the detected ambient temperature is greater than or equal to the predetermined temperature,
• wherein the correction data include a calibration curve that is a quadratic or higher-degree curve, and
• the storage stores first coefficients applied to the calibration curve when the ambient temperature detected by the temperature sensor is less than the predetermined temperature, and second coefficients, that is different from the first coefficient, applied to the calibration curve when the ambient temperature detected by the temperature sensor is greater than or equal to the predetermined temperature.
