PROBLEM TO BE SOLVED: To prevent a piezoelectric element from electrostatic discharge.SOLUTION: A method is provided for manufacturing a piezoelectric element including a piezoelectric layer, a first electrode formed on one side of the piezoelectric layer, and a second electrode formed on the other side of the piezoelectric layer. The method includes a first step of forming the wiring for bringing the first and second electrodes into the same electric potential, and a second step of invalidating a function for keeping the same electric potential of the first and second electrodes using the wiring. The second step is included in a step of cutting out a plurality of chips by cutting a substrate, and thereby the wiring is cut by the cutting-out. |
