Abstract
The invention is a nonwoven fabric characterized by satisfying 0.25≤(L/V)≤10, when an average fiber diameter of all fibers is L (μm) and a volume per mis V (cm). The nonwoven fabric leads to a solid electrolyte-carrying sheet in which solid electrolyte particles are carried between fibers and which can achieve a good balance among thickness reduction, powder falling property of the solid electrolyte particles, and electrical conductivity.
