PROBLEM TO BE SOLVED: To provide a radiation panel for a ceiling to prevent hearing of an outdoor sound at an indoor place through a position in the ceiling. SOLUTION: A pipe mat M where a plurality of heat exchange pipes 4 are formed in a mat-form state is laid on a panel body, and a heat insulation material 8 is overlapped on the pipe mat M. The two ends of the heat insulation material 8 are surrounded by a support part 9. On the assumption of a radiation panel P for a ceiling fixed at a panel body 1, a sound insulation member 10, such as a gypsum board, is interposed in a removable state between the support part 9 and the heat insulation material 8. |
