Abstract
A laminated body formed by laminating a fiber substrate composed of a plurality of fibers and a polymer layer formed from a polymer latex. The polymer layer covers the fiber substrate in a state in which a portion of the polymer layer has permeated among the fibers. A ratio (t1/d) of a thickness t1 of the portion of the polymer layer that has permeated among the fibers (from a top surface of the fiber substrate) to a substrate layer average thickness d is 0.1 to 0.95. A thickness t2 of the portion of the polymer layer covering the top surface of the fiber substrate (from the top surface of the fiber substrate) is 80 μm or more.

A laminated body formed by laminating a fiber substrate composed of a plurality of fibers and a polymer layer formed from a polymer latex, wherein
- the polymer layer covers the fiber substrate in a state in which a portion of the polymer layer has permeated among the fibers;
- a ratio (t1/d) of a thickness of a permeated polymer layer t1 to a substrate layer average thickness d is 0.1 to 0.4, where the thickness of the permeated polymer layer of the polymer layer, which is a portion that has permeated among the fibers, from a top surface of the fiber substrate is set to t1 [μm] and a substrate layer average thickness of the fiber substrate is set to d [μm];
- the thickness of the permeated polymer layer t1 is 50 to 600 μm;
- a thickness of a top surface polymer layer t2 [μm] is 180 μm or more, where the thickness of the top surface polymer layer of the polymer layer, which is a portion covering the top surface of the fiber substrate, from the top surface of the fiber substrate is set to t2 [μm];
