Abstract

PURPOSE:To improve a yield, by forming a cavity part at a part corresponding to the vibratory plane of a piezoelectric vibrator element between an organic resin layer and an armor resin layer. CONSTITUTION:After wax 9 is applied on a position outside of the organic resin layer 8 and equivalent to the center part of the vibratory plane of the piezoelectric vibrator 1 so that its outer plane can offer a smooth projecting plane, the armor resin layer 10 is formed on the wax 9 and the outer periphery of the organic resin layer 8. Furthermore, by performing a baking process in such state, the wax 9 is penetrated into the armor resin layer 10 due to the heat of baking, and a cavity 5 is formed in an area where the wax 9 occupies, that is, the area between the organic resin layer 8 and the armor resin layer 10.
