Abstract
A wheel apparatus includes a substrate rotatable around a rotation axis, and a plurality of optical elements respectively formed in a plurality of regions different from each other around the rotation axis on the substrate and having wavelength characteristics different from each other. The regions of the plurality of optical elements are adjacent to each other via boundary lines including linear sections. The linear sections of the boundary lines intersect with respective straight lines along the radius of the substrate at the same intersection angle greater than 0 degrees and less than 90 degrees.
