PROBLEM TO BE SOLVED: To provide a touch pad with an antenna, configured to reduce the influence of noise of the antenna.SOLUTION: A touch pad 1 with an antenna includes: a substrate 20 having an operation surface 11 with a predetermined operation area 11 arranged at the top; a capacitive detection electrode group arranged in an area corresponding to the operation area 11a of the substrate 20; and the antenna 28 for radio communication, which is arranged below the substrate 20 in an area overlapping an electrode formation area where the capacitive detection electrode group is formed in top view. The capacitive detection electrode group includes a first electrode group 25 extended in a predetermined first direction, and a second electrode group 26 extended in a second direction orthogonal to the first direction. The antenna 28 is extended in a direction crossing the first and second directions. |
