Abstract: A method of manufacturing a gyro element as a vibration element is a manufacturing method of processing a quartz crystal substrate to form an outward shape of a gyro element including a vibrating arm and form recessed portions in a vibrating arm. The method includes forming the outward shape of a gyro element from one surface of the quartz crystal substrate using dry etching and forming the recessed portions using wet etching.
