A contact detecting device includes a plurality of detecting elements, a generating unit, and a determining unit. The plurality of detecting elements are related to one another in a two-dimensional configuration on a predetermined contacted surface, and respectively detect a contact of an object with the contacted surface. The generating unit generates, on the basis of the result of detection by the plurality of detecting elements, feature information representing a feature of a trajectory drawn on the basis of a contact of an object with the contacted surface. The determining unit determines whether or not the feature information generated by the generating unit corresponds to previously registered specific contact feature information representing a feature of a trajectory drawn on the basis of a specific contact of an object with the contacted surface.
