To provide a laminated fiber sheet which shows the degree of its fiber adhesiveness not as high as that of a nonwoven fabric formed by a wet process and can be applied to various use applications.

The laminated fiber sheet of more than one layer is formed of at least a single nonwoven fabric composed of an extremely thin fiber with a fiber diameter of 4 μm or less and a fiber length of 3 mm or less, and/or a fine fiber with a fiber diameter of 4 to 50 μm and a fiber length of 10 mm or less, and further, with a coating build-up of a deposit of 0.5 mass% or less. In addition, this sheet includes a region where fiber sheet layers, each having a different average fiber diameter, are adjacent to each other.
