Zusammenfassung:Provided are a capacitance-type input device and a capacitance-type input method with which it is possible to determine which of a plurality of touch switches has been touched. A capacitive input device includes: a plurality of touch switches; and a determination unit that determines, on the basis of the outputs of the plurality of touch switches, a touch operation to any one of the plurality of touch switches. The determination unit performs a first comparison for comparing a first threshold value used in the determination of the presence or absence of the touch operation with each of the outputs of the plurality of touch switches. Performing a second comparison of comparing an output greater than the first threshold value among the outputs of the plurality of touch switches with a plurality of comparison threshold values which are greater than the first threshold value and are different from each other; on the basis of a comparison result obtained in the first comparison or the second comparison, a touch op
