PROBLEM TO BE SOLVED: To provide a ceiling panel member, by which a ceiling structure can be simplified and the efficiency of ceiling construction works can be improved, and the ceiling structure. SOLUTION: The ceiling panel member 11 has a panel member body 25 and an optical transmission section 27. In the panel member body 25, an optical reflecting film 23 is formed on the top face of a rectangular tabular body 21 composed of a light transmitting material, and illumination light L1 introduced from the side end face 21a of the tabular body 21 is projected from the underside of the tabular body 21. In the optical transmission section 27, signal light L2 for communication is transmitted to the tabular body 21 of the panel member body 25 in a transmissible manner, and the terminal sections 27a-27d of the optical transmission section 27 are installed at the specified position of the side end face 21a of the tabular body 21. A ceiling panel is constituted by combining the ceiling panel members 11 in a plane shape while a specified optical transmission line is configured of the optical transmission sections 27. A light source for illumination is disposed around the constituted ceiling panel. |
