Abstract
A surface mount type piezoelectric vibrator comprises a piezoelectric vibrator having a piezoelectric vibrating piece bonded to an airtight terminal with a lead terminal and sealed by a cylindrical bottomed metal sealing tube. An electrode terminal is connected to the lead terminal so that a tip of the electrode terminal is disposed approximately at the same position as a tip of the lead terminal in a longitudinal direction of the surface mount type piezoelectric vibrator. The piezoelectric vibrator is coated with a mold resin.
