PROBLEM TO BE SOLVED: To provide a piezoelectric component 1 that prevents sealing property of a space formed around a vibration part of a piezoelectric element 5 from being deteriorated, and secures a wide internal space of a recess near the vibration part of the piezoelectric element 5. SOLUTION: The piezoelectric component 1 includes: the piezoelectric element 5 including a piezoelectric substrate 2 and a first vibration electrode 3 and a second vibration electrode 4 attached to each of both main surfaces of the piezoelectric substrate 2 facing each other across the piezoelectric substrate 2; a support substrate 6 where the piezoelectric element 5 is disposed on one main surface while securing the space for vibration around it; and a case 9 which is provided with a recess 7 for housing the piezoelectric element 5, wherein the entire surface around the opening of the recess 7 is bonded to one main surface of the support substrate 6 by an adhesive sheet 8. The adhesive sheet 8 is attached from the surface around the opening to the inner wall of the recess 7 over the entire periphery around the opening of the recess 7. COPYRIGHT: (C)2011,JPO&INPIT |
