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.

The invention claimed is: 1. A method for manufacture of moisture absorptive and desorptive paper, wherein the method includes a step for preparation of an aqueous slurry and a step for manufacture of paper by using said aqueous slurry by a wet method, wherein said aqueous slurry contains organic fine particles having a 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 selected from the group consisting of wood pulp, non-wood pulp and fibrillated synthetic fiber, and wherein the step for preparation of an aqueous slurry and the step for manufacture of paper are conducted with water where the concentration of cations excluding the metal ions bonded to said acidic group is not more than 1 ppm.
