Abstract
In a color separation prism that includes a first and second prism blocks bonded to each other, the first and second prism blocks are bonded to the first and second adhesive portions of the first and second base plates, respectively. The first and second base plates are fixed to the first and second base plate-fixing portions of a base with the first and second base-fixing portion interposed therebetween, respectively. The second adhesive portion is disposed between the first and second base plate-fixing portions so that a direction in which the second base plate-fixing portion is displaced from the first base plate-fixing portion and a direction in which the second adhesive portion is displaced from the second base-fixing portion are opposite to each other in a case in which the base and the second base plate expand or contract due to a change in temperature.
