<p>PURPOSE:To provide a raw material directly used as a material for a building and a packaging container and additionally furnished with a moisture absorbing and moisture discharging function. CONSTITUTION:A moisture absorbing material 1 is mainly constituted of a core material 2 and a skin material 3 and a back material 4 respectively adhered on both main faces of the core material 2. The core material 2 has a large number of through holes 5 passing through in the thickness direction, and in each of the through holes 5, a moisture absorbent (for example, silicagel) capable of displaying a moisture absorbing and moisture discharging function is charged. The skin material 3 is a moisture permeable sheet. This moisture absorbing material 1, when it is arranged in a high humidity atmosphere, absorbs moisture in the air in a moisture absorbent 6 through the skin material 3. Conversely, when it is arranged in a dry atmosphere, it discharges the moisture absorbed in the moisture absorbent 6 through the skin material 3.</p> |
