Abstract
According to one embodiment, an electrostatic actuator includes a substrate, an electrode unit, a film body unit, and an urging unit. The electrode unit is provided on the substrate. The film body unit is provided to oppose the electrode unit and is conductive. The urging unit is configured to support the film body unit and includes a connection unit connected to the substrate and an elastic unit provided between the connection unit and the film body unit. A contacting state and a separated state are possible for the electrode unit and the film body unit according to a voltage applied to the electrode unit. The elastic unit has a branch portion between one end of the elastic unit connected to the connection unit and multiple one other ends of the elastic unit connected to the film body unit.
