To provide laminated paper excellent in adhesiveness to a laminated resin film and highly-fine printability on its outer surface without disturbing effects of contained various agents while using an aqueous adhesive.

The laminated paper has a weight-average fiber length of disintegrated pulp of the laminated paper obtained by disintegration according to the JIS P 8220 of 0.5 to 1.2 mm, a moisture vapor transmission measured according to the JIS Z 0208 of 4,500 to 9,000 g/m2 in 24 h, a Stockigt-sizing degree measured according to the JIS P 8122 of 0.5 to 7 sec, a wet tensile strength measured according to the JIS P 8135 of not less than 0.15 kN/m, and a unit weight measured according to the JIS P 8124 of 25 to 50 g/m2. The paper is used as the laminated paper laminated with a plurality of sheets of resin raw material having moisture-permeability and gas-permeability.
