1. A method of producing an electroconductive cellulose-based film by coating a cellulose-based film with a coating solution containing a binder, superfine particles and a solvent to form an electroconductive layer thereon,
wherein the coating solution comprises at least one kind of glycol monoalkyl ether containing solvent selected from the group consisting of ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, propylene glycol monomethyl ether, and propylene glycol monoethyl ether in an amount of 20 to 40% by weight based on the total solvent, and a ketone-containing solvent in an amount of 20 to 50% by weight based on the total solvent,
wherein the superfine oxide metal particles have an average particle diameter of 80 nm or less.
