In a microelectromechanical device, a mobile mass is suspended above a substrate via elastic suspension elements and is rotatable about said elastic suspension elements, a cover structure is set above the mobile mass and has an internal surface facing the mobile mass, and a stopper structure is arranged at the internal surface of the cover structure and extends towards the mobile mass in order to stop a movement of the mobile mass away from the substrate along an axis (z) transverse to the substrate. The stopper structure is arranged with respect to the mobile mass so as to reduce an effect of reciprocal electrostatic interaction, in particular so as to minimize a resultant twisting moment of the mobile mass about the elastic suspension elements.
