An object of the present invention is to provide an ultrafine cellulose fiber-containing sheet, in which generation of warp (curl) is suppressed. The present invention relates to a laminated sheet having two or more layers of sheet comprising ultrafine cellulose fibers with a fiber width of 1000 nm or less, wherein among two or more layers of the sheet, when the thickness (m) of the thickest sheet is defined as T.sub.max and the thickness (m) of the thinnest sheet is defined as T.sub.min, the value of T.sub.max/T.sub.min is 3 or less, and the thickness of a single layer of the sheet is 15 m or more.
