Abstract
A movable device simultaneously enabling reduction of size down to the submicron level, higher speed operation, a streamlined production process, low costs, and greater reliability. A movable device provided with bottom electrodes and a basic conductive layer fixed to a substrate, an elastic shaft of a carbon nanotube with a bottom end fixed on the basic conductive layer and standing up, and a top structure including a top electrode spaced away from the bottom electrode and fixed to a top end of the elastic shaft, wherein when applying voltage between a bottom electrode and the top electrode, the top electrode displaces relatively to the bottom electrodes within an allowable range of elastic deformation of the elastic shaft.
