Abstract
A marker () includes a lenticular lens () formed from a translucent material to have a plurality of convex portions () positioned to line up in, for example, at least one direction. The optical axes (OA) of the convex portions () all intersect with an optical reference point (OP) on the product optical axis (PA). The optical axes (OA) of the convex portions () are all orthogonal with and pass through the center of the bottom surfaces of grooves (). Colored portions () are accommodated in the grooves ().
