<p>PROBLEM TO BE SOLVED: To provide a method for manufacturing a piezoelectric element thinner than limited in manufacture, which is considered difficult, and to provide a method for manufacturing an optical lens. SOLUTION: A method for working with a piezoelectric element is provided where, firstly, a vibration part of such shape as to discriminate crystal orientation of the piezoelectric material is formed at the central part of square or rectangular Quartz Blank. Secondary, at the central part of the first vibration part where such shape as to discriminate crystal orientation is firstly formed, a second round or circular vibration part which does not discriminate crystal orientation of the piezoelectric material is formed.</p> |
