Abstract

PURPOSE:To produce simply the step lead part material for vibrators by utilizing an etching process. CONSTITUTION:By holding the base of a tuning a fork crystal vibrator piece by step lead part material 22, the impulse-proof property and the work efficiency where the vibrator is fitted to a circuit can be improved. In respect to lead part material 22, the linear material is cut by a required length as shown in (a). Then, after resistor film A is formed on a part of this material as shown in (b), this materail is soaked in etching liquid and is taken out from etching liquid at the time when the lead part material becomes a desired thickness as shown in (c), and resistor film A is removed. Thus, the lead part material which has desired- length diameter large part 22a can be produced simply.
