Abstract
There is provided a method of manufacturing a piezoelectric vibrator element capable of preventing the piezoelectric vibrator element from being damaged when segmentallizing the piezoelectric vibrator element. The method of manufacturing a piezoelectric vibrator element includes the steps of providing the wafer with the piezoelectric plate and a frame part adapted to support the piezoelectric plate via a connection part, providing a pair of excitation electrodes to the piezoelectric plate, and forming a pair of extending electrodes extending from the piezoelectric plate to the frame part through the connection part and electrically connected respectively to the pair of excitation electrodes, and segmentallizing the piezoelectric plate by cutting the connection part. In the step of providing the pair of excitation electrodes, the pair of extending electrodes are formed on a side surface of the connection part.
