PROBLEM TO BE SOLVED: To provide a compact optical switching device in which components are efficiently arranged to make a case small. SOLUTION: The optical switching device includes: at least a light input means and a light output means; an optical path transforming element; a driving part; and an optical component fixing member, wherein all of the light input means and the light output means are arranged facing to the incident face of the optical path transforming element, and the light input means and the light output means are so arranged that the respective optical axis lines are parallel to each other, the light input means and the light output means are independently supported by respective supporting members and fixed on an optical component fixing member, one of the adjacent two light input means and the light output means is arranged at a position closer to the incident face of the optical path transforming element than the other, at least a part of the supporting member supporting one of the light input means and the light output means is located between the supporting member supporting the other light input means or the light output means and the incident face of the optical path transforming element in the optical axis line direction.
