Abstract
A non-woven fabric that absorbs only a small amount of volatile low molecular weight compound, and that has good texture when used as a non-woven fabric that makes contact with human skin. This thermal bond non-woven fabric containing cyclic olefin resin includes at least: fibers (A) containing at least 50 mass % of a cyclic olefin resin (A1) having a glass transition temperature Tg° C.; and fibers (B) containing at least 10 mass % of either a cyclic olefin resin (B1) having a glass transition temperature Tg° C., or a crystalline thermoplastic resin (B2) having a melting point Mp° C.; the fibers (A) and the fibers (B) being heat-spliced together; wherein Tg>Tgor Tg>Mp, and either the difference between the glass transition temperature Tg° C. and the glass transition temperature TgB1° C. or the difference between the glass transition temperature Tg° C. and the melting point Mp° C. exceeds 20° C.
