けたことを特徴とする圧電共振子。 A tuning fork portion is formed by carving a plurality of slits on one end side of a piezoelectric substrate having a substantially right-angled rectangular planar shape, and a flat surface disposed opposite to the piezoelectric substrate and the tuning fork portion of the piezoelectric substrate. A covering sheet is bonded under pressure to a substantially right-angled square spacer via an adhesive layer formed on both sides of the spacer so as to surround the tuning fork portion, and between the spacer and the one end side of the piezoelectric substrate. In a piezoelectric resonator in which a part of the adhesive layer is allowed to penetrate to form a gap to ensure a vibration space for the tuning fork part,
Pressing the covering sheet around the piezoelectric substrate and the spacer on the one end side of the piezoelectric substrate and/or the part facing the one end side of the spacer and corresponding to the adhesive layer; A piezoelectric resonator characterized in that a notch is provided through which a part of the adhesive layer enters.
