Abstract: This marker has: an optically transparent convex plastic lens section having a first surface that includes convex surface sections and flat surface sections, and a second surface that includes first regions and second regions other than the first regions, the second surface being disposed in a position on the reverse side to the first surface; a section to be detected that is formed in the first regions and/or the second regions; and a positioning section formed in those regions of the second surface that correspond to the flat surface sections, the positioning section indicating positions in the first regions that correspond to the convex surface sections. The first regions are concave sections or convex sections disposed in those regions of the second surface that correspond to the convex surface sections.

Abstract: This marker comprises a plurality of convex-surface section disposed along the X-axis direction and a plurality of detection sections disposed so as to face the convex-surface sections. Each of the detection sections is located, in the protruding direction of the convex-surface sections, closer to the convex-surface section side than a focal point on an image surface of the convex-surface section of the first optical unit in the X direction and is located on a single plane located further on the opposite side from the protruding direction than the edge of the image surface. The image surface extends from the first optical unit to the nth optical unit in the X direction, where n is at least 2.

Abstract: A transparent resin is injection molded to create a marker (10) as an integrally molded article (lenticular lens portion (11)) including convex surfaces (112) and recesses (113) formed on the rear side of the convex surfaces. The recesses (113) are filled with coating films (115) formed by applying and curing a fluid coating material. Each recess (113) is arranged corresponding to a convex surface (112) so that the coating films (115) can be observed as optically distinguishable from the side of the convex surfaces (112).
