Abstract
A piezoelectric component in which leakage of vibration is suppressed and vibration characteristics are excellent is provided. A piezoelectric component of the invention includes a support substrate; and a piezoelectric element mounted on the support substrate. The piezoelectric element includes electrodes (vibration electrodes) on one main surface and the other main surface of the piezoelectric element so that the electrodes have an area facing each other, and a concave area extending in a width direction of the piezoelectric element, in at least one of excepted areas which are areas other than the electrodes facing each other of the one main surface and the other main surface. At least part of corner portions of the concave area which extend in the width direction forms a curved surface.
