Claim:
1. A capacitive touchscreen, comprising: a first electrode layer including a plurality of first electrodes, the first electrodes being arranged at spaced intervals along a first direction; a second electrode layer including a plurality of second electrodes, the second electrodes being arranged at spaced intervals along a second direction so as to cross the first electrodes, the second direction crossing the first direction; and at least one interlayer interposed between the first electrode layer and the second electrode layer, wherein: the at least one interlayer has a thickness set such that a coupling capacitance between each first electrode and each second electrode is between or equal to 0.5 pF and 2 pF, the second electrodes include an endmost second electrode located at an end in the second direction, the first electrode layer further includes a plurality of first wires connected to the first electrodes, the first wires each including a first parallel portion extending substantially parallel to the second electrodes, the first parallel portions of the first wires include a closest first parallel portion located closest to the second electrodes, the closest first parallel portion extending at a minimum distance of 0.4 mm in the second direction from the second electrodes, and a capacitance of a first electrostatic coupling is substantially less than a capacitance of a second electrostatic coupling, where the first electrostatic coupling is between the closest first parallel portion and the endmost second electrode, and the second electrostatic coupling is of an intersection where the endmost second electrode crosses one of the first electrodes connected to one of the first wires having the closest first parallel portion.
