Zusammenfassung:	A method for fitting a paper sheet that allows paper sheets to be easily fitted to each other, and a paper molded article including a fitting portion are provided. A method for fitting a paper sheet includes a water absorption step of causing a region of a paper sheet to absorb water, the region being at least a part of the paper sheet; a placing step of placing the region of the paper sheet caused to absorb water, such that the region is located between one set of first molding surfaces of a press mold; a molding step of molding, using the one set of first molding surfaces, the region of the paper sheet caused to absorb water into a three-dimensional shape, by closing the press mold; a layering step of layering another paper sheet that is not caused to absorb water on the paper sheet molded, after opening the press mold; a fitting step of fitting the paper sheet molded and the another paper sheet that is not caused to absorb water by closing the press mold to mold, using the one set of first molding surfaces, a laminate into a three-dimensional shape; and a taking-out step of taking out a molded article including a fitting portion, after opening the press mold.
