PROBLEM TO BE SOLVED: To provide a radiation panel in which performance per unit area is improved.SOLUTION: A radiation panel includes a panel part 1 and a heat exchange pipe 2 inside which a heat medium flows. The heat exchange pipe 2 includes a plurality of straight parts 21 parallel with each other along the panel part 1, and a connection part 22 connecting end parts of adjacent straight lines among the straight parts 21 to each other and shifting the flow direction of the heat medium. The parallel straight parts 21, 21 are parallel so as to alternately have a wide gap and a narrow gap. The connection part 22 is bent with a bend radius of a minimum radius or more allowed in processing. The panel part 1 includes a body part 111 and a pipe support part 112. |
