Abstract
According to one embodiment, a touch panel includes first interconnections, second interconnections, sensor units and a control unit. The first interconnections are arranged along a first direction, and extend along a second direction intersecting with the first direction. The second interconnections are arranged along a third direction intersecting with the first direction, and extend along a fourth direction intersecting with the third direction. The sensor units are provided in intersection portions of the first and second interconnections, include first and second ferromagnetic layers, and an intermediate layer, allow a current to be passed, and have one end connected to the first interconnections and another end connected to the second interconnections. The control unit is connected to the first and second interconnections. An electric resistance of the sensor units changes in accordance with a stress applied. The control unit senses a change in the electric resistance.
