PROBLEM TO BE SOLVED: To provide an optical element supporting device which is small in the angle at which the optical axis of the luminous flux after passage through the optical element inclines with the optical axis of the luminous flux before incidence on the optical element in spite of moving of the optical element and does not entail an increase of the external form and dimensions or the weight of the device. SOLUTION: This optical element supporting device has a moving section 100a having the optical element 36, a supporting member 100c for movably supporting the moving section movably in at least the first direction with respect to a fixing section 100b and driving means CL and PM for driving the moving section in the first direction. The optical element is arranged with respect to the incident luminous flux so as to minimize the range where the luminous flux after the passage through the optical element inclines with respect to the incident luminous flux on the optical element within the moving direction in the first direction of the moving section. |
