Abstract
Moisture absorptive and desorptive paper having both high moisture absorptive and desorptive properties and high dimensional stability is provided. Moisture absorptive and desorptive paper comprising organic fine particles having cross-linking structure and 1 to 10 mmol/g of acidic group where not less than 1 mmol/g of metal ion of at least one kind of metal selected from the group consisting of Li, Na, K, Mg and Ca is bonded to said acidic group, inorganic fiber and pulp-shaped fiber. By the basic constitution as above, on one hand the moisture absorptive and desorptive properties inherent to the organic fine particles are efficiently utilized by suppressing the use of binder as much as possible, and on the other hand deformation or thermal shrinking of the paper due to swelling in water at the time of absorption etc. is able to be suppressed.
