Abstract

PURPOSE:To simplify works to enhance productivity and reduce the cost by providing the linkage part for preventing the removal of a crystal oscillation piece and two cases on the same side. CONSTITUTION:Linkage part 4 dependent upon half etching for preventing the removal from crystal plate 3 is provided in the side of the root part of crystal oscillation piece surrounded by crystal frame 2. Similarly, linkage part 7 dependent upon half etching for preventing the removal from crystal plate 8 is provided in the side of the root part of crystal case 9. Then, crystal oscillation piece 1 and crystal case 9 are sealed hermetically by junction material 10 and are held in crystal plates 3 and 8 by linkage parts 4 and 7 dependent upon half etching which are processed in the same side as crystal oscillation piece 1 and crystal case 9. As a result, the separation from the crystal plate after sealing becomes very easy, so that productivity can be enhanced and the cost can be reduced.
