A touch sensor includes: a plurality of electrodes; and a plurality of sensing wires connected with the respective electrodes, and formed by extending in a first direction, wherein at least one of the electrodes includes a resistance element which has a shape that is at least partially bent in a unit electrode region and has a resistance value that is changed to correspond to a pressure of a touch. A touch location and pressure can be sensed with the same elements, so that the touch sensor may have increased function yet remain thin.
