Zusammenfassung:	PROBLEM TO BE SOLVED: To enable even the use of a near-infrared absorbent of low heat resistance by a method wherein a hard coat layer containing the near-infrared absorbent is provided at least on one surface of a transparent resin layer and a visible light beam transmittance and a near-infrared transmittance are made specific values. SOLUTION: A near-infrared absorbing resin molded article is constituted by providing a hard coat layer containing a near-infrared absorbent on one surface of a transparent resin layer at least. The 400-700nm visible light beam transmittance of this near-infrared absorbing resin molded article is made 50% or above and the 800-1000nm near-infrared transmittance thereof is made 10% or below. As for transparent resin, polycarbonate resin, poly(meta)acrylic acid ester resin, cyclic olefin resin, saturated polyester resin, polystyrene, polyvinyl chloride, polyvinyl acetate or the like is used. By this method, it is made possible to use even a near-infrared absorbent of low heat resistance and also to improve visible light beam transmitting properties.
