Abstract
An Al electrode structure for a zinc oxide thin film in which an intermediate layer of V.sub.2 O.sub.3, Ta, V, Cu, Ni or Ti is provided between the surface of the zinc oxide thin film and the Al electrode. A tuning fork vibrator equipped with such an electrode structure has high reliability in that changes in resonance frequency and series resonance resistance (Ro) with time are small.
