A fingerprint sensor includes a piezoelectric substrate, and an electrode on the piezoelectric substrate. The electrode includes a first electrode and a second electrode on at least one of one surface of the piezoelectric substrate and an opposite surface opposite to the one surface. The electrode includes a node area in which the first electrode crosses the second electrode, and the node area transmits and receives a signal by an object that makes contact with the node area or approaches the node area in a direction of the piezoelectric substrate. The fingerprint sensor includes a substrate including a first area to a fourth area. At least one of first and second electrodes is provided in the first area to the third area, and a chip connected with the first and second electrodes is provided in the fourth area.
