摘要： In the case where an ultraminiature piezoelectric substrate, which has a resonating portion formed by making a concavity by etching in the surface of the piezoelectric substrate made of an anisotropic crystal material, is mass-produced by batch operation using a large-area piezoelectric substrate wafer, an annular portion surrounding each concavity is formed sufficiently thick to prevent cracking from occurring when the wafer is severed. A piezoelectric substrate 2 of an anisotropic piezoelectric crystal material has a thin resonating portion 4 and a thick annular portion 5 integrally surrounding the outer marginal edge of the resonating portion to form a concavity 3 in at least one of major surfaces of the substrate; the inner wall 5a of the annular portion in the one crystal orientation slopes gently more than the inner wall in the other crystal orientation perpendicular to said one crystal orientation, and the piezoelectric substrate is longer in said one crystal orientation than in the other crystal orientation.

摘要： The object of the present invention is to provide an angular velocity sensor that uses Coriolis force with a flatly supported double tuning fork structure that uses an in-plane asymmetrical flexural secondary mode. A large support area is used to provide a high-precision angular velocity sensor with superior resistance to vibration and impact. A double tuning fork gyro-sensor is formed integrally from: two arms; a driver electrode formed on the arms; and a double tuning fork supporting the ends of the arms. Also included are: a detection module connected to the double tuning fork support section; a detection electrode formed on the detection module; and a support securing section for the detection module. When there is rotation, the Coriolis force acting on the arms is transferred to the detection module by way of the double tuning fork support section so that an in-plane asymmetrical flexural secondary vibration takes place.
