Abstract
The mirror device has a mirror, and a supporting mechanism which elastically supports the mirroron a substratein a state in which the mirror floats from the substrate, so that the mirror can be inclined in an arbitrary direction. The supporting mechanism has three supporting partsA,B andC that mechanically connect the substrateand mirror. Each of the supporting partsA,B andC has one or more plate spring partsthat are constructed from a thin film consisting of one or more layers. One end portion of each plate spring partis connected to the substratevia a leg partwhich has a rising part that rises from the substrate. The other end portion of the plate spring partis mechanically connected to the mirrorvia a connecting part which has a rising part that rises from this other end portion. The mirroris supported on the substrateonly via the plate spring partof the respectiveA,B andC. As a result, compactness and mass production characteristics can be greatly improved while maintaining superior optical characteristics.
