ABSTRACT:
The substrate for devices 10 comprises an insulating substrate 12 of an insulating material, conducting layers 14 formed on the insulating substrate 12 and opposed to each other at a certain distance, and a dielectric film 16 formed on that portion of the insulating substrate 12 between the conducting layers 14. The substrate 10 incorporates a capacitance constituted by the opposed electric layers 14 and the dielectric film 16. A piezoelectric oscillator 20 is connected to the left and right conducting layers 14b, 14c of the substrate for devices 10. A cap 22 is connected to a boundary part of the substrate 10 through epoxy resin 24. The substrate for devices 10 with a built-in capacitance can reduce fabrication costs of a piezoelectric oscillation device and a surface acoustic wave device.
