PROBLEM TO BE SOLVED: To obtain a moisture-absorptive soundproof material having humidity conditioning properties capable of being applied to a building interior-finishing material or a ceiling material and excellent soundproofness and heat-insulating properties. SOLUTION: (1) A particle aggregation type porous body layer contains moisture absorption and desorption pulverulent bodies of 1-100 pts.wt. and a binder of 5-30 pts.wt. in terms of solid contents to an inorganic particulate matter of 100 pts.wt. having a grain diameter of 5.0 mm or less. (2) A board with a plurality of through-holes is used as basic constitution, and the board is laminated on one surface or both surfaces of the particle aggregate type porous body layer. |
