Abstract
A method of producing an electromagnetic wave shielding sheet by which an electromagnetic wave shielding sheet having a high shielding property against an electromagnetic wave and having low cost is produced. The method of producing an electromagnetic wave shielding sheet includes; preparing a dispersion containing carbon nanotubes, an inorganic pigment, sodium carboxymethyl cellulose, and water; and drying the dispersion. In the dispersion, a ratio of a mass of the inorganic pigment to a mass of the carbon nanotubes is 1/4 or more and 1 or less.
Claims5
