An input device includes a capacitive sensor and a piezoelectric sensor. The piezoelectric sensor is positioned on the front side of the capacitive sensor in a front-to-back direction from the front to the back of the input device, and is configured to change its output in response to a force applied to the piezoelectric sensor from its front side. The piezoelectric sensor includes a piezoelectric layer and a first electrode and a second electrode positioned across the piezoelectric layer from each other in the front-to-back direction. The capacitive sensor includes a capacitive sensing area where the capacitive sensor is configured to perform a sensing operation. The first electrode and the second electrode of the piezoelectric sensor do not overlap the capacitive sensing area when viewed in the front-to-back direction.
