Abstract:
1. A piezoelectric vibrating device, comprising: a piezoelectric vibrating piece that vibrates when electrically energized; a first package plate having an inner main surface defining a recess, the recess having volume and dimensions sufficient to contain at least a portion of the piezoelectric vibrating piece, the inner main surface including a peripheral main surface that peripherally extends around the recess; and a second package plate having inner and outer main surfaces, the inner main surface being bonded to the peripheral main surface of the first package plate using a sealing material that thus seals the piezoelectric vibrating piece inside a package formed of the first and second package plates, the sealing material including multiple concentric bands of sealing glass and multiple concentric bands of adhesive, the sealing-glass bands and the adhesive bands circumscribing the recess.
