<P>PROBLEM TO BE SOLVED: To provide a piezoelectric vibration gyroscope element exerting an excellent impact-resistant property even when the piezoelectric vibration gyroscope element is dropped, and to provide a piezoelectric oscillating gyroscopic sensor using the same. <P>SOLUTION: The piezoelectric vibration gyroscope element is equipped with: a base part 31 fixed to a package; two support arms 32, 32 formed so as to extend from both sides of the base while being spaced from each other; driving arms 34, 34 connected to respective head sections of the two support arms in a direction perpendicular to the support arms; and two detecting arms 36, 36 formed so as to extend from both sides of the base part 31 in a direction perpendicular to the support arms while being spaced from each other. Cross-section sizes of the support arms 32, 32 are adjusted so as to prevent them from resonating with vibrations generated when they are dropped. <P>COPYRIGHT: (C)2008,JPO&INPIT |
