Abstract
A method of manufacturing a piezoelectric component includes forming an unhardened first elastic material partially on at least a pair of end portions of a piezoelectric element, the pair of end portions including an edge portion of the piezoelectric element, hardening the first elastic material, forming an unhardened second elastic material on the entire circumference of the piezoelectric element and the first elastic material, hardening the second elastic material, forming an unhardened outer-cladding resin on the entire circumference of the second elastic material covering the piezoelectric element and the first elastic material, and hardening the outer-cladding resin.
Claims8
A method of manufacturing a piezoelectric component, comprising the steps of:
- forming an unhardened first elastic material partially on at least a pair of end portions of a piezoelectric element, the pair of end portions including an edge portion of the piezoelectric element;
- hardening the first elastic material;
- forming an unhardened second elastic material on an entire circumference of the piezoelectric element and the first elastic material;
- hardening the second elastic material;
- and
- forming an unhardened outer-cladding resin on the entire circumference of the second elastic material covering the piezoelectric element and the first elastic material;
- and
- hardening the outer-cladding resin;
- wherein
- the total thickness of first and second elastic materials at the edge portions of the piezoelectric element is larger than a difference between the maximum contraction amount of the outer-cladding resin and a maximum contraction amount of the piezoelectric element.
