At the same time, the piezoelectric element is held between the piezoelectric elements by the strong spring properties of the two lead portions whose main surfaces are substantially on the same plane, thereby preventing the piezoelectric element from falling off. Further, the stopper portion that substantially closes a substantial portion of the bottom opening of the holding portion prevents the piezoelectric element from moving toward the lead portion, thereby increasing the holding stability of the piezoelectric element, and also provides a gap between the holding portion and the piezoelectric element. Make it easy for molten solder to accumulate between the Then, the force melting solder wraps around the space between the holding part and the piezoelectric element, and the extraction electrode is formed on the same surface of the piezoelectric element, regardless of the surface on which the extraction electrode of the piezoelectric element is formed. The lead electrode and the holding part are electrically connected reliably through the solder even when they are formed on different surfaces. Further, the solder filled in a considerable amount between the two electrodes also functions as a damping material that absorbs vibrations propagating from the vibrating portion of the piezoelectric element and prevents spurious waves.

It is inserted into the holding parts 14, 14, brought into contact with the stopper part 15, removes the force that held the terminals 5, 5 open, and holds the piezoelectric resonant element 4 in a predetermined position by its springiness. At this time, the piezoelectric vibrating element 4 has a lead portion 11,
It is reliably held by the strong elastic force in the width direction (direction substantially perpendicular to the thickness direction) of No. 11. Then, by passing solder between the piezoelectric resonant element 4 and the holding portions 14, 14, they are electrically connected. When soldering, hold the two soldering irons at the same time from the direction A in Figure 3.
