Abstract: PROBLEM TO BE SOLVED: To reduce leaking of electromagnetic waves and near IR rays, to obtain excellent chroma, brightness and antireflection property and to reduce the cost by forming a film containing at least a dye and/or a near IR ray absorbent and an electrically conductive inorg. film on a substrate. SOLUTION: A film containing at least a dye and/or a near IR ray absorbent, and an electrically conductive inorg. film are formed on a substrate. The film containing the dye and/or the near IR ray absorbent is formed on both faces or one face of the substrate, and the electrically conductive inorg. film is preferably formed on the opposite face. The film containing the dye and/or the near IR ray absorbent is formed on the substrate preferably by a wet coating method such as a spin coating, die coating and dipping method. As for the film containing the dye and/or the near IR ray absorbent, a thin film containing a thermoplastic resin such as an acrylic resin, or a thermosetting resin such as an epoxy resin, or a hardened body of a hardening compd. such as a silane compd. as a matrix component can be used.
