Provided is a method for inspecting a piezoelectric element in which voltage is applied to a piezoelectric element and evaluation of the electrical characteristics of the piezoelectric element is performed. The method includes a first step in which the piezoelectric element is held on a flat plate-shaped slightly adhesive sheet and a second step in which voltage is applied to the piezoelectric element held on the slightly adhesive sheet and evaluation of the electrical characteristics of the piezoelectric element is performed.
