A touch-type input device equipped with: a touch panel wherein multiple drive electrodes and multiple sensor electrodes are arranged in a grid-like pattern wherein capacitors are formed at the intersections between the drive electrodes and the sensor electrodes; and a controller that detects touch operations with respect to the operation surface of the touch panel. The controller determines whether a touch operation has occurred on the basis of a data group indicating the amount by which the electrostatic capacitance changes from a standard value that is set in advance for each capacitor. When activated the controller sets the standard value by acquiring the parasitic capacitance for each capacitor, and when it is determined on the basis of a range of variation (A) for the parasitic capacitance of the multiple capacitors that an erroneous standard value has been acquired, the parasitic capacitance is reacquired (S23).
