Abstract:
1. A piezoelectric vibrator comprising: a hermetically closed casing comprising first and second substrates with a cavity inside, the first substrate being formed with at least one through-hole; an electrode film formed along an inner surface of the through-hole so as to become conductive between ends of the through-hole, wherein the electrode film does not extend beyond the through-hole; a piece of glass filing the through-hole which is melted and solidified in the through-hole to hermetically close the through-hole; and a piezoelectric vibrating strip secured inside the cavity and electrically connected via a conductive pattern to the electrode film in the through-hole in a first direction, wherein the conductive pattern is extended to cover the through-hole along a second direction, wherein the first direction is perpendicular to the second direction.
