PROBLEM TO BE SOLVED: To provide a ceiling radiation system having high radiation efficiency and excellent design performance. SOLUTION: A corrugated heat transfer plate 200 in which a plurality of heat transfer projections 220 each having a long and thin shape in the forward/backward direction and bent downwardly and a plurality of heat transfer recesses 210 bent upwardly are continued in the right/left direction is arranged below a ceiling face RF. Cold water is made to flow to a plurality of heat absorbing condensation pipes 100 arranged in at least part of the plurality of heat transfer recesses 210 of the corrugated heat transfer plate 200 and is condensed. Peripheries of the heat absorbing condensation pipes 100 are cooled by thermal radiation and the heat transfer recesses 210 located in the peripheries are also cooled successfully. Since this cooling is transmitted to the heat transfer projections 220 with excellent thermal conductivity, an indoor space is cooled by thermal radiation by the overall corrugated heat transfer plate 200.
