摘要：
Disclosed is an oscillation device comprising: a first movable plate adapted to be oscillated about a first rotation axis; a first elastic supporting portion for oscillatively supporting the first movable plate; a supporting substrate for fixing the first elastic supporting portion; a first magnetic field generating portion arranged in a position remote from the first movable plate; a second movable plate adapted to be oscillated about a second rotation axis; and a second elastic supporting portion fixed to the first movable plate for oscillatively supporting the second movable plate, in which a first coil is provided in the first movable plate to be turned round the second movable plate, and in which a second magnetic field generating portion is provided in the second movable plate. The oscillation device is capable of: operating at a high speed with large displacement; enhancing an energy efficiency; and oscillating about two axes.
