A terminal device includes a display device and a position detection sensor configured to detect a position indicated by an electronic pen on the display screen. The position detection sensor includes: a plurality of first electrodes spaced apart along a first direction on a first surface of an insulating layer, and one or more first linear members extended in a direction along the first electrodes and arranged in each space between two of the first electrodes having a predetermined distance from each other in the first direction, among the plurality of first electrodes, on the first surface of the insulating layer. Each of the plurality of first electrodes of the position detection sensor, upon receiving an electric current, generates a magnetic field.
