A pressure sensing unit, a capacitive hybrid sensor device, and an input apparatus using the same are provided. The pressure sensing unit for detecting pressing events includes a pressure sensing pad group and a floating conductive element. The pressure sensing pad group includes a first pressure sensing pad, a second pressure sensing pad, and a ground pad that are spaced apart from one another. The first pressure sensing pad and the second pressure sensing pad are electrically shielded from each other by the ground pad. One of the floating conductive element and the pressure sensing pad group is configured to be movable in a movement direction relative to another one of the floating conductive element and the pressure sensing pad group. The floating conductive element overlaps with the pressure sensing pad group in the movement direction.
