There is described a capacitive touchscreen with improved responsivity, and which reduces a possibility that a control unit coupled to the touchscreen, such as a detection IC, is brought into a saturated state. A touchscreen T1 includes a first electrode layer 200a, a second electrode layer 200b, and interlayers 100a, 500b, and 300b. The first electrode layer 200a includes a plurality of first electrodes 210a. The first electrodes 210a are arranged at spaced intervals along a first (Y-Y') direction, and each extend in a second (X-X') direction. The second electrode layer 200b includes a plurality of second electrodes 210b. The second electrodes 210b are arranged at spaced intervals along the second (X-X') direction, and each extend in the first (Y-Y') direction so as to cross the first electrodes 210a. The interlayers 100a, 500b, and 300b are interposed between the first electrode layer 200a and the second electrode layer 200b. The interlayers 100a, 500b, and 300b have thicknesses such that a coupling capacitance of each first electrode 210a and each second electrode 210b is from 0.5 pF to 2 pF. |
