Zusammenfassung:	To provide a marker which is unnoticeable, and a marker step-and-repeat imposition body.SOLUTION: A marker 1 is formed by depositing a first reflection layer 20 reflecting visible light and near infrared rays and a near infrared ray absorbing layer 30 for absorbing at least near infrared rays, on each other. The first reflection layer 20 is partially removed for the near infrared ray absorber layer 30, and has a mark 2 displayed as a dependent shape by near infrared rays reflected by layers other than the near infrared ray absorber layer 30. This makes it possible to make the mark 2 unnoticeable under visible light and to observe the mark 2 under near infrared rays.SELECTED DRAWING: Figure 2 【課題】人の目に目立たないマーカー、マーカー多面付け体を提供する。【解決手段】マーカー１は、可視光、及び、近赤外光を反射する第１反射層２０と、少なくとも近赤外光を吸収する近赤外光吸収層３０と、が重ねて配置されており、第１反射層２０は、近赤外光吸収層３０に対して一部が抜けており、近赤外光吸収層３０以外の層が反射する近赤外光により独立した形状として表示されるマーク２を備える。これにより、可視光ではマーク２が目立たず、近赤外光ではマーク２を識別可能に観察可能となる。【選択図】図２
