In a method of manufacturing a heat exchanger tube sheet sealing elements are arranged on respective ends of heat exchanger tubes. Said ends of the heat exchanger tubes having the sealing elements are arranged at predetermined positions in a mold. Said ends of the heat exchanger tubes are sealed such that a tube sheet material to be casted in the mold does not enter the heat exchanger tubes during casting of the tube sheet material. A tube sheet material is casted in the mold for covering the sealing elements. The tube sheet material is hardened in the mold.
