<p>PROBLEM TO BE SOLVED: To provide a hygroscopic panel, a hygroscopic body and a hygroscopic sheet which make use of the hygroscopic, deodorizing and antibacterial functions of charcoal in place of a dehumidifying material such as a water-absorption polymer or calcium chloride. SOLUTION: A hygroscopic panel 30 is formed by dividing the inside of an outer frame 11 into a plurality of small chambers 13 by means of dividing component 12, sealing small pieces and crushed materials 20 of charcoal, bamboo charcoal or the like in the small chambers 13 and closing at least one face of the panel by a ventilating covering sheet. Or the hygroscopic panel 30 is constituted by inserting a hygroscopic body 40, in which small pieces or the crushed materials 20 of charcoal, bamboo charcoal or the like are wrapped in the uniform thickness by a ventilating covering sheet 14. Otherwise, else, a hygroscopic sheet is manufactured by using the above-mentioned hygroscopic body 40 or inserting the same into a flexible cloth cover.</p> |
