Abstract

PURPOSE:To secure more precise temperature compensation as well as to miniaturize the circuit block as a whole by storing the temperature compensating capacitor into the same container as the crystal oscillator. CONSTITUTION:Crystal oscillator bar 9 is supported be crystal lead terminal 18 and via the solder, and terminal 18 is connected electrically to the outside via the sealed part comprising sealing ring 15 and sealing glass 16. On the other hand, temperature compensating capacitor 12 is adhered to the insulated plate 14 via the adhesive, and plate 14 is adhered to lower case 13 via the adhesive each. At the same time, capacitor 12 is adhered to lead terminal 17 via the solder, and terminal 17 is connected electrically to the outside via the sealing part. Case 13 is pressure- bonded to upper case 10 with sealing, and the inside of case 13 is kept under the highly vacuum state. Thus, crystal oscillator 9 and capacitor 12 can be formed into a unit.
