METHOD FOR MANUFACTURING HUMIDITY CONTROL BOARD, AND THE HUMIDITY CONTROL BOARD

PROBLEM TO BE SOLVED: To provide a method for manufacturing a humidity control board which has strength and a moisture control function capable of being used for a building material. SOLUTION: After a humidity control material 4 and a synthetic resin fibers-containing nonwoven fabric 3 for the prevention of the coming-off of the humidity control material are interposed between upper and lower fiber mats 2 and 1 so as to form a laminated body 5, a needle 17 is inserted through the laminated body 5 so that needle punching can be applied to the laminated body 5. Subsequently, after the synthetic resin fibers of the nonwoven fabric 3 are heated and melted at a temperature equal to/higher than a melting point of the fiber of the synthetic resin, they are cooled and solidified so that the upper and lower fiber mats 2 and 1 can be joined together by using the solidified resin as an anchor.
