Abstract
A piezoelectric angular velocity meter includes a piezoelectric element. The piezoelectric element includes a first piezoelectric element and a second piezoelectric element bonded to the first piezoelectric element. The second piezoelectric element includes a second member made of a piezoelectric crystal, and upper- and lower-surface electrodes sandwiching the second member. The first piezoelectric element is fixed to the upper-surface electrode of said second piezoelectric element with an adhesive. The first piezoelectric element includes a first member made of a piezoelectric crystal, upper-surface electrodes, and a lower-surface electrode. The upper- and lower-surface electrodes sandwich the first member of the first piezoelectric element. The piezoelectric element is supported by two support portions.
