PROBLEM TO BE SOLVED: To provide a piezoelectric device which allows the reduction of the probability that wiring electrodes on a flexible substrate are disconnected, an input device, a display device, and an electronic apparatus.SOLUTION: The piezoelectric device includes: a base 2; a piezoelectric element 7 which has a front surface 7a connected to the base 2 and has a first terminal electrode 71 on a rear surface 7b thereof; a flexible substrate 8 which includes a base member 81, a wiring electrode 82 provided on the base member 81, and a first coating layer 83 provided on the base member 81 to expose a part of the wiring electrode 82 and cover the rest, wherein the exposed part of the wiring electrode 82 functions as a second terminal electrode 821; and an anisotropic conductive adhesive 9 which is provided on the second terminal electrode 821 apart from the first coating layer 83 and electrically connects the first terminal electrode 71 and the second terminal electrode 821. The second terminal electrode 821 located between the anisotropic conductive adhesive 9 and the first coating layer 83 overlaps the piezoelectric element 7 in plan view. |
