A touch sensor includes a touch sensing region, a touch sensing electrode in the touch sensing region, a touch extending wire extended to the touch sensing electrode, a touch pad on an end of the touch extending wire, a flexible printed circuit board overlapping the touch pad, a flexible printed circuit pad on the flexible printed circuit board and facing the touch pad, and a conductive bonding member between the touch pad and the flexible printed circuit pad. The conductive bonding member is bonded to each of the touch pad and the flexible printed circuit pad. The touch pad includes a first touch pad layer made of a transparent metal oxide, and a second touch pad layer on the first touch pad layer. The second touch pad layer is made of a metal material. The conductive bonding member is bonded to the second touch pad layer.
