A supporting device that supports an optical element in a gravitational force direction, the supporting device comprises: a supporting member to be connected via an adhesive to an outer circumference of the optical element, the supporting member including a plurality of members each of which has a projection for supporting the optical element. Each of the plurality of members is arranged to have a rigidity lower than that of the adhesive in a direction orthogonal to the gravitational force direction.
