Beschreibung
Zusammenfassung:	The present invention provides a marker that can prevent reflection from the surface of the marker and can project an image with an excellent contrast. The marker (100) of the present invention includes a lens main body (110). The lens main body (110) has multiple lens portions (103) on one surface side and has multiple detectable portions (105) on the other surface side. The lens portions (103) are arranged successively in a planar two-dimensional direction. On the one surface, a pitch of the lens portions (103) in a one-dimensional direction is narrower than a pitch of the lens portions (103) in the other one-dimensional direction.
