<P>PROBLEM TO BE SOLVED: To provide a near-infrared ray absorbing material having reflected color tone exhibiting no blue color, effectively absorbing near-infrared rays, having high visible light transmittance and excellent transparency. Ž<P>SOLUTION: A near-infrared ray absorbing material 1 with visible light transparency is provided by laminating a near-infrared ray absorbing layer 3 and a cholesteric liquid-crystalline layer 4 on a substrate 2, wherein the near-infrared ray absorbing layer 3 includes a resin and an inorganic near-infrared ray absorbing agent having a 40-200 nm average particle diameter and the cholesteric liquid-crystalline layer 4 includes a cholesteric liquid-crystalline material having a fixed cholesteric structure and a selective reflection wavelength in the red light region.
