CAPACITANCE SENSOR AND INFORMATION INPUT APPARATUS

摘要

A capacitance sensor is provided and includes at least one electrode group positioned within a sensor area. The electrode group including a first electrode, a second electrode, and a third electrode. The capacitance sensor also includes a drive section configured to measure capacitances of the first, second and third electrodes, and configured to determine position information of at least one object based on the measured capacitances. At least one of the electrodes includes a portion that both increases and decreases in height along a width direction of the sensor area.
