A color wheel including a disk-shaped substrate made of a light-transmittable medium and a plurality of filters arranged on the substrate is fabricated. Each filter is capable of selectively transmitting rays of light having a desired wavelength. The method of fabricating the color wheel including the steps of forming at least one of a plurality of adjoining selective color-transmittable films as the filters each at a predetermined area on a front side of the disk-shaped substrate, and utilizing, as a mask for exposure from a back side of the disk-shaped substrate, a portion containing at least one of two borders with which each one of the plurality of adjoining selective color-transmittable films is defined.
