<P>PROBLEM TO BE SOLVED: To provide a piezoelectric oscillator and piezoelectric vibrator capable of dealing with making the piezoelectric oscillator and the piezoelectric vibrator highly functional and making them into compound device. <P>SOLUTION: In a piezoelectric vibrator, within the identical cavity 7 of the same sealed container 1, at least two or more piezoelectric vibrating blanks 11, 12 are housed and on the piezoelectric vibrating blanks 11, 12, exciting electrodes 18, 19 are formed. The piezoelectric vibrators are packaged within the hermetically sealed container 1 so as not to overlap the exciting electrode 18, 19 portions thereof. <P>COPYRIGHT: (C)2007,JPO&INPIT |
