Abstract
The present invention provides a laminated nonwoven fabric achieving both handling properties during manufacturing and use and adherence to a skin surface at a high level particularly when used for a face mask. The laminated nonwoven fabric includes a nonwoven fabric layer (A) and a nonwoven fabric layer (B). The nonwoven fabric layer (A) is formed from a fiber A having a single fiber diameter of 50 nm or more and 800 nm or less, and the nonwoven fabric layer (B) is formed from a fiber B having a single fiber diameter of 3 μm or more and 30 μm or less. The nonwoven fabric layer (B) includes 15 to 40% by mass of a fiber B1 to all of the fibers constituting the nonwoven fabric layer (B), the fiber having tensile strength of 2.0 cN/dtex or less as measured based on JIS L 1015: 2010 8.7.2. The nonwoven fabric layer (B) Includes a fiber B2 having tensile strength exceeding 2.0 cN/dtex as measured based on JIS L 1015: 2010 8.7.2. The nonwoven fabric layer (A) is disposed as an outermost layer of at least one surface.
