ABSTRACT:
There is provided a color wheel which includes: a color filter disk having a side surface; and a rotary member having a circumferential surface and adhesively attached to the center portion of the color filter disk. In the color wheel described above, a portion of an adhesive for fixing the rotary member to the color filter disk sticks out on the side surface of the color filter disk along the circumferential surface of the rotary member, and the portion of the adhesive sticking out, when hardened, functions as a barrier to prevent uncured portions, if any, of the adhesive present between the two components from getting scattered out in the radial direction on the side surface of the color filter disk when the color wheel is rotated at a high speed during the inspection process, thus improving the production yield rate.
