Abstract
This piezoelectric wafer has: a piezoelectric vibration piece; a frame portion that supports the piezoelectric vibration piece; and a coupling portion that couples the piezoelectric vibration piece to the frame portion. A pair of first and second metal bumps is formed in juxtaposition on the piezoelectric vibration piece. The coupling portion has slits extending in its width direction except in a bridge, i.e., a part of the coupling portion in its width direction. An end in the width direction of the bridge is distantly spaced from the first and second metal bumps both in a direction perpendicular to the width direction of the coupling portion with no overlap with these metal bumps.
