An input device according to the technology disclosed herein is one which is disposed on a user side of a display device, and includes a pair of coordinate detection electrodes that are disposed to face each other via a dielectric element. One of the pair of the coordinate detection electrodes is disposed on flexible film bonded on a surface on the user side of the display device. Electrodes of the display device serve as the other of the pair of the coordinate detection electrodes. Flexible film includes an extension part which extends from a detection region where the one of the coordinate detection electrodes is disposed. The extension part includes wiring parts which electrically couple to the coordinate detection electrodes and electrically and mechanically couple to connection parts that are disposed on the display device.
