Abstract
In a method for manufacturing a piezo-electric vibrator, a vibrator is provided having a vibrator piece and a frame surrounding a periphery of the vibrator piece. A first exciting electrode is formed on the vibrator piece. A weight is disposed on the vibrator piece in spaced-apart relation to the first exciting electrode. A characteristic of the vibrator is then adjusted. The first exciting electrode is removed and a metal film is formed on a surface of the vibrator. The metal film is patterned and a second exciting electrode is formed on the vibrator piece.
