PROBLEM TO BE SOLVED: To provide an adsorption core which can enhance the rigidity of a heat medium pipe while improving heat transfer performance between the heat medium pipe and an adsorbent, and its manufacturing method.SOLUTION: In an adsorption core which comprises a heat medium pipe 21 in which a heat medium circulates, and an adsorbent 24 which adsorbs water vapor at the outside of the heat medium pipe 21 by being cooled by the heat medium, and releases the adsorbed water vapor by being heated, the heat medium pipe 21 has a core material 21a composed of metal which is higher than copper in hardness, and a coated layer 21b which is composed of copper, and coats an external surface of the core material 21a, a mixed sintered body formed of copper powder 23b and the adsorbent 24 is arranged at a peripheral part 22 of the heat medium pipe 21a, and the copper powder 23b and the heat medium pipe 21 are metal-bonded to each other. |
