摘要： The present invention provides a tuning fork shaped oscillator, an angular velocity sensor element, and an angular velocity sensor with improved breaking strength with respect to CI and drive power, CI stability, and frequency stability. The present invention relates to a tuning fork shaped crystal oscillator of a configuration wherein two tuning fork shaped crystal elements that have been formed by wet etching during the process of forming the external shape of a tuning fork, in such a manner that the longitudinal direction of the tuning fork is aligned on the Y-axis of the crystalline axes (XYZ) and also the lateral direction thereof is aligned on the X-axis, are bonded together with the ±X-axis directions thereof oriented in opposite directions; and the right side surface of each of the two tuning fork shaped crystal elements is the +X face of the crystal when the two tuning fork shaped crystal elements are viewed in an upright attitude.

摘要： A manufacturing method produces an angular velocity sensor element easily with a high degree of accuracy. The manufacturing method includes forming a number of tuning fork shaped crystal elements on a single crystal wafer by a photo-etching technique, the crystal elements having protrusion ridge line sections in the lengthwise direction of +X faces of the crystal, caused by etching anisotropy. A step is included for forming a metallic film on each side face including both principal planes and said +X face of said tuning fork shaped crystal element of the single crystal wafer. The method also includes dividing the metallic film of the +X face along the protrusion ridge line section and forming first and second sensor electrodes.
