A touch sensor device includes a calibration processor that calibrates capacitance of each of a plurality of capacitance sensors. The calibration processor calculates an initial calibration value when the touch sensor device is activated, and maintains the initial calibration value when a calibrated capacitance calculated with the initial calibration value exceeds a touch determination threshold value. If the calibrated capacitance calculated with the initial calibration value does not exceed the touch determination threshold value even after a specified period elapses subsequent to calculation of the initial calibration value, the calibration processor obtains a value equal to or approximate to a minimum value of the capacitance that changes in accordance with a re-touch as a recalibration value when the calibrated capacitance represents an anomaly of the initial calibration value.
