    Abstract: Integrated gyroscope (1) including a suspended mass (10); mobile actuation electrodes (11) extending from the suspended mass; and a sensing mass (6) connected to the actuation mass (10) through coupling springs (25). The suspended mass (10) is formed by an external part (10a) and an internal part (10b), electrically separated by an electrical-insulation region (23) having a closed annular shape. The electrical-insulation region (23) is laterally completely surrounded by the external part (10a) and by the internal part (10, 10b). In one embodiment, the suspended mass (10) has the shape of a closed frame delimiting an opening (18), the sensing mass (20) is formed inside the opening (18) and is connected to the internal part (10b), and the mobile actuation electrodes (11) are connected to the external part (10a).
