Conductive sheet and electrode

Disclosed is a conductive sheet which contains a structure wherein a sheet (A) that has an apparent specific gravity of 0.05-0.50 g/cm 3 and is composed of fibers having a diameter of 3-20 μm, and a sheet (B) that is composed of fibers having a diameter of not more than 3 μm are laminated. The both surfaces of the conductive sheet have a surface resistivity of not more than 10 Ω/□. Also disclosed is an electrode which is formed of the conductive sheet and contains at least an active material. The sheet (A) may be a fibrous material which is formed using an organic polymer as a main component.
