To provide a thin film having high conductivity, capable of effectively exerting a leakage electromagnetic wave shielding effect, having a high total light transmission factor, generating no moire interference pattern, and usable as an electrode at a low cost by forming it with a fine mesh structure made of silver.
This transparent conductive film is made of a metal having low volumetric specific resistance, particularly silver, into a fine mesh structure, and it has a high light transmission factor while maintaining high conductivity. When the average opening diameter of meshes exceeds 50 μm in the transparent conductive film having the fine mesh structure, the mesh structure can be recognized via naked eyes, visibility becomes inferior, therefore the average opening diameter is set to 50 μm or below. When the average opening diameter/average line width is smaller than 7, the area of the opening portion becomes relatively narrow, the total light transmission factor of 60% or above is difficult to secure, therefore the average opening diameter/average line width is set to 7 or above.
