    • PROBLEM TO BE SOLVED: To provide an optical article for IR communication and a light receiving unit for IR communication, capable of specifically largely transmitting only a wavelength range in the IR communication band and visually showing white by scattering and reflecting light in a visible light region. SOLUTION: A scattering reflection layer 23 is formed by uniformly dispersing fine particles in a transparent binder resin, the fine particles having a refractive index different from that of the binder resin. The particle diameter D of a part of or the whole of the fine particles is controlled to be represented by D COPYRIGHT: (C)2010,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide an optical article for infrared-ray communication and a light receiving unit for infrared-ray communication, capable of specifically largely transmitting only a wavelength region in an infrared-ray communication band and visually showing a white color by scattering and reflecting light in a visible light region.SOLUTION: A port 12 for infrared-ray communication and infrared-ray control is provided to a case main body 11 of a portable information terminal. In the case main body 11, a light-receiving unit 14 consisting of a light-emitting element and a light receiving element and the like is arranged against the port 12. A light receiving part 13 for infrared-ray communication is mounted on the port 12. Fine particles with a refraction index different from that of the light receiving part 13 are uniformly dispersed in the light receiving part 13 to make the fine particles scatter and reflect light in the visible light region to develop a white color. Simultaneously, thin film particles having a band specifically low in transmission factor in the visible light region are uniformly dispersed in the light receiving part 13 to suppress transmission of the light in the visible light region by the thin film particles.
