Abstract
[Solving Means] A composite-optical-system unit includes a polarization beam splitter and a thermal conduction member. The polarization beam splitter includes a first prism including a first surface, a second prism including a second surface having an area different from an area of the first surface, and an overlap interface on which the first surface is attached to and overlaps the second surface. The thermal conduction member is thermally connected to a connection region being a region other than the overlap interface of the first surface or the second surface having an area larger than an area of the other surface.
