In the container, the crystal blanks are respectively held in different spaces, which are isolated from one another by a shielding member. Hereby, respective crystal blanks are electrically shielded from one another. As the plurality of crystal blanks, a crystal blank of AT cut for generating a communication frequency signal, and a tuning fork type crystal blank for generating a clock signal are preferably used. |
