摘要
In an optical switch according to the present invention, a galvo plate is caused to abut against a base plate on its mount portions at the both ends, and in addition, abutting sections formed at portions near galvano-mirrors are also caused to abut against the base plate. As a result, heat transfer from the galvo plate to the base plate is improved, and heat in the galvano-mirrors, particularly heat in its drive circuit and heat due to a laser, can be dissipated to the base plate. This allows the implementation of multi-channelization in which a plurality of optical path changing elements are arranged with ease and high-accuracy, and also facilitates the heating of the optical path changing elements.
