<P>PROBLEM TO BE SOLVED: To provide a piezoelectric device including a sealing structure which prevents a sealing material from flowing in a storage space and stably secures joining strength and airtightness. <P>SOLUTION: A piezoelectric vibration piece 5 is mounted and connected to a main surface of a base 4, and a lid 3 has a flange and a recessed inner surface. The flange and the base are sealed so that the piezoelectric vibration piece 5 is housed, and the lid 3 has a continuous curve surface which continues from the flange to the inner surface. A piezoelectric device 1 having these features and a method for manufacturing the piezoelectric device 1 are provided. <P>COPYRIGHT: (C)2012,JPO&INPIT |
