The manufacturing method of the present invention comprises: a first step for modifying a surface of the carbon nano-materials; a second step for producing a dispersion liquid of the carbon nano-materials with a reduced work function; a third step for producing an one-component-type coating liquid by blending a metal nanowire and the dispersion liquid of the carbon nano-materials having the reduced work function in the second step; and a fourth step for producing a film by spreading the coating liquid produced in the third step on a substrate.
