The support body has an opening part with first and second rectilinear sections extending parallel to each other. The support film blocks off the opening part. The first piezoelectric element straddles the first rectilinear section from an interior area to an exterior area of the opening part as seen in plan view. The first elastic part straddles the first rectilinear section from the interior area to the exterior area of the opening part. The second elastic part straddles the second rectilinear section from the interior area to the exterior area of the opening part. The first and second elastic parts respectively have first and second elastic end sections disposed in the interior area of the opening part and spaced apart from each other.

摘要： Provided is a method for manufacturing a piezoelectric element that has excellent piezoelectric characteristics and can be made into a thicker film. A piezoelectric thin film is crystallized by a process in which piezoelectric precursor films 4021 through 4025 containing the metal elements of a piezoelectric ceramic are coated with a material, dried, pyrolyzed, and then heat-treated under prescribed conditions in a diffusion furnace. With this method, a piezoelectric thin film can be made into a thicker film without initiating cracking.
