<p>PROBLEM TO BE SOLVED: To provide a nanofiber nonwoven fabric containing a metal oxide as a main component that is excellent in flexibility and tensile strength.SOLUTION: The nanofiber nonwoven fabric is mainly composed of a nanofiber containing a metal oxide as a main component and having a fiber diameter of 0.2μm to 1.0μm, and has a flexural rigidity of 0.01 to 0.05×10NM/m and a flexural hysteresis of 0.01 to 0.20×10NM/m. The component constituting the nanofiber may have an amorphous structure or the component constituting the nanofiber may comprise a crystal phase having a crystallite diameter of 2.4 to 11.8 nm.</p> |
