| 1. A color wheel comprising:
a plurality of sectorial color filter segments, each color filter segment having at least one segment fixing mechanism constituted
by one of a through-hole and a cavity; and
a support member having a plurality of protrusions disposed at an outer peripheral portion thereof, the protrusions each has
a cavity defined therein, the protrusions being fitted in respective segment fixing mechanisms of the color filter segments
thereby fixedly setting the color filter segments to the support member in a disk-like arrangement,
wherein the support member is formed by press-molding so as to integrally include the protrusions.
