摘要：
An electrostatic actuator is disclosed that includes a deformable oscillating plate (12) that is deformed by
electrostatic force, an electrode (14) that is arranged opposite the oscillating plate via a gap (13) formed by sacrificial layer (27) etching, a connection path (15) that is connected to the gap, an atmosphere connecting hole (16) that connects the connection path to the exterior, and a resistance path (45) arranged between the atmosphere connecting hole and the connection path. The resistance path is configured to resist penetration of a sealing agent for sealing the atmosphere connecting hole into the connection path.
