PURPOSE:To secure the constant support state before and after enclosure of the oscillator as well as to realize high anti-impact performance, high accuracy and miniature size, by fitting and fixing the support board of the oscillator to the protrusion provided to the substrate or the like of the container. CONSTITUTION:Hermetic glass frame 13 of the hermetic sealing terminal, for example, is used for the protrusion provided to substrate 8 of the container, and the outer circumference part of the side surface is made uneven. Support board 14 formed from the elastic material such as the fluororesin silicon resin or the like is fitted and fixed to the uneven part to hold fixedly the bevel surface rectangular thickness shear oscillator bar 3 which is bevel-formed. Support board 14 and 14' touch inner wall 8a of the substrate at least at the area located under the oscillator bar and has no contact to inner wall 9a of the cover at any area. In such constitution, the inner wall suppression pressure has no fluctuation even before and after the junction between the substrate and the cover as well as during the junction. Thus, oscillator bar can be supported under the constant state. |
