GYROSCOPE SENSOR AND METHOD FOR MANUFACTURING THE SAME

PROBLEM TO BE SOLVED: To provide a gyroscope sensor which is excellent in the detection accuracy of an angular velocity, and especially enables its vibrator to be mounted to a package having a flat basal plane, and to provide a method for manufacturing the gyroscope sensor which enables an operation test to be carried out in such a multiple string state that a base of the vibrator is connected. SOLUTION: The gyroscope sensor includes: the vibrator 25 formed of an SOI substrate 33; and a package 40 for containing the vibrator 25. The vibrator 25 is configured to include: the base 17 and arms 15, 16 which are formed on an upper silicon substrate 13; and a pedestal 34 formed of a lower silicon substrate 11 below the base 17 through an insulating layer 12. The pedestal 34 is bonded to a package basal plane 40a, and an allowance space 41 for coping with the downward displacement of the arms is formed between the basal plane 40a and the arms 15, 16.
