Abstract: A touch sensor includes a substrate, a touch input unit, a plurality of wires, and a pad unit. The touch input unit is disposed on the substrate and includes a plurality of sensing electrodes for sensing user touch. The pad unit includes a plurality of pads electrically connected to the sensing electrodes through the wires. The pads include a first pad. The first pad includes a first conductive film disposed on the substrate, an insulating film disposed on the first conductive film, and a second conductive film disposed on the insulating film. The insulating film includes a plurality of first-type holes and a plurality of second-type holes. Each first-type hole of the first-type holes is smaller than each second-type hole of the second-type holes.
