PROBLEM TO BE SOLVED: To provide an optical path device which is capable of drastically reducing a manufacturing cost and time, providing better stability and performance at high temperature, preventing the same from shifting, deforming and breaking and further can be applied to various kinds of projection systems. SOLUTION: The optical path device comprises a plurality of reflectors 301-304 and at least one sleeve 305 for completely or partially covering the reflectors 301-304, wherein the reflectors 301-304 are piled together to form an optical path 306 as a hollow pipe, allowing light to pass therethrough.
