A vibrating gyroscope (1) in which the provision of leads for connecting divided electrodes (6a, 6b) to external circuits is not required includes a vibrator (2) having a first piezoelectric substrate (3) and a second piezoelectric substrate (4). Two divided electrodes (6a, 6b) are formed on the main surface of the first piezoelectric substrate (3), while a common electrode (7) is disposed on the main surface of the second piezoelectric substrate (4). The vibrator (1) is supported by a first support pin (8) and a second support pin (9), both formed generally in an "L" shape. The support pins (8, 9) are attached to the vicinity of the nodes on the divided electrodes (6a, 6b), respectively. A third support pin (10) is formed generally in a "U" shape and is bonded at its intermediate section to the vicinity of the node on the common electrode (7). The first and second support pins (8, 9) not only support the vibrator (2), but are also electrically connected to the divided electrodes (6a, 6b), respectively, and are also coupled to external circuits. This can eliminate the need for providing leads for connecting the divided electrodes (6a, 6b) to the circuits. <IMAGE> |
