Abstract
An electrode structure for a zinc oxide thin film having a SnO.sub.2 layer between the surface of the zinc oxide thin film and the electrode. A tuning fork vibrator equipped with such a structure has a high reliability in that changes in resonance frequency and insulation resistance (IR) with time are small and the increase in series resonance resistance (R.sub.O) is small.
