The present invention provides a manufacturing method of a nano conductive film. The manufacturing method comprises the following steps of: dissolving a nano material of a conductive substance into asolvent, and dispersing the nano material to form a uniform conductive substance solution; performing suction filtration on the conductive substance solution by using a microfiltration membrane, and attaching the conductive substance to the microfiltration membrane after suction filtration; performing normal-temperature air drying or low-temperature drying on the microfiltration membrane attachedwith the conductive substance; and after the microfiltration membrane is completely dried, stripping the conductive substance layer attached to the microfiltration membrane from the microfiltration membrane to obtain the conductive membrane. According to the invention, the gravity of the solution is utilized, the microfiltration membrane is used for filtering to form a flat conductive membrane, and then the conductive memb
