A carbon fiber non-woven fabric comprising an aggregate of ultrafine carbon fibers having a fiber diameter of 0.001 to 2 μm, and a method for producing the same. This nonwoven fabric is useful as a base material for fuel cell electrodes, a precursor, and an electrode material. Further, it can be mixed with a resin to be used as a composite material, and it can be further used as a filter by supporting a metal. |
