  "textContent": "To measure the distance between a sensing target and sensors accurately by suppressing differences in amount of change in outputs from sensors and differences in initial capacitances thereof and detect the sensing target highly accurately, capacitance-type sensor includes: sensor electrodes 1 to 5 configuring a sensor electrode group 6; and a pair of guard electrodes 28a and 28b. The sensor electrodes 1 to 5 are driven being supplied with a sensor potential or a guard potential, and the guard electrodes 28a and 28b are driven being supplied with the guard potential. Even when the outermost sensor electrode 1 or 5 of the sensor electrode group 6 is activated, the amount of change in the outputs from the sensor electrodes 1 to 5 configuring the sensor electrode group 6 and their capacitance values can be made substantially uniform because the guard electrodes 28a and 28b are driven at the guard potential.",
