Summary:A sensing device includes first sensor elements allocated on a two-dimensional plane, and a second sensor element allocated on the same plane as the first sensor element and operating according to a manner different from that of the first sensor element. A signal processing unit generates a fingerprint image based on an output signal of the first sensor element after detecting placement of a finger based on an output signal of the second sensor element, and collates the generated fingerprint image with a previously registered fingerprint image. A capacitance type sensor element is used as the first sensor element, and a pressure sensitive sensor element is used as the second sensor element.
