PROBLEM TO BE SOLVED: To provide a method for manufacturing a piezoelectric sensor that is easy to perform positioning between a ground electrode layer and a signal electrode.SOLUTION: A method for manufacturing a piezoelectric sensor includes: a stacking step that stacks and integrates a first ground electrode layer 21 on one surface of a long piezoelectric sheet 1, and also stacks and integrates a signal electrode 41 and a second ground electrode layer 31 with an electrically-insulated state from each other on the other surface of the piezoelectric sheet 1, and thereby manufactures a laminated sheet B; and a cut-off step that cuts off the laminated sheet B. The first ground electrode layer 21 is formed in a long band shape and also the second ground electrode layer 31 is formed in a long band shape. The signal electrode 41 is repeatedly formed with a prescribed interval in the longitudinal direction of a third electric insulating sheet 42 on one surface on the long third electric insulating sheet 42. The laminated sheet B is cut off at a place between adjacent signal electrodes 41. |
