Abstract
A lid and an insulating bonding layer that seal a piezoelectric vibrator on a substrate are bonded with higher strength. A piezoelectric vibration component includes a substrate having a principal surface on which a piezoelectric vibrator is mounted, an insulating film disposed on the principal surface, a lid having a recess opening toward the principal surface and an edge portion around the recess. Moreover, first and second insulating bonding layers are interposed between the lid and the substrate. The first and second insulating bonding layers are joined together between the edge portion and the insulating film so as to seal the piezoelectric vibrator in a space between the recess and the principal surface.
