PROBLEM TO BE SOLVED: To provide a heat exchanger of a circulating fluidized bed boiler capable of improving durability by suppressing vibration from side to side and up and down generated in a heat transfer pipe by increasing rigidity. SOLUTION: A heat transfer pipe array A is structured by bending and arranging a plurality of the heat transfer pipes 31 vertically, and connecting a plurality of parts in a vertical direction by heat transfer pipe connection members 35. A plurality of the heat transfer pipe arrays A are arranged in a horizontal direction, and upper ends and lower ends are connected to upper part support members 37 and lower part support members 39, respectively, to structure a heat transfer pipe block B. A one-body heat transfer pipe support part C is structured by connecting the upper part support members 37 and the lower part support members 39 of the heat transfer pipe block B by block connection members 40, 41.
