Abstract
A printed material () has a base substance (), an absorption part () (a near infrared ray absorbing layer ()) that is provided on the base substance () to contain a near infrared ray absorbing material, and a code shape () that is formed in a predetermined shape from the absorption part () or by covering a part of the absorption part () and that outputs code information (CI), upon irradiation with light of near infrared rays, as reflected light of the light of near infrared rays, where in the near infrared ray absorbing material, in a case where an integral value of transmittance of visible light at 400 nm to 750 nm is denoted as a first integral value X1, and an integral value of transmittance in a 20 nm width that is centered on a predetermined wavelength λ of the light of near infrared rays is denoted as a second integral value X2, a ratio R=X2/X1 between the second integral value X2 and the first integral value X1 is 0.09 or more.
