A conductive film () includes: a resin film base () having a hard coat layer () on one main surface of a resin film (); an underlying layer () on a hard coat layer-formed surface of the resin film base; and a metal thin film () on the underlying layer. The underlying layer includes at least one layer of inorganic dielectric thin film. The hard coat layer contains first fine particles having an average primary particle diameter of 10 to 100 nm. In a cross section of the hard coat layer, the proportion of an area occupied by the first fine particles is preferably 10% or more.

Conductive film, method for manufacturing conductive film, and temperature sensor film

Provided is an electroconductive film having a metal thin-film on a resin film base; and a temperature sensor film which is obtained by patterning the metal thin-film on the resin film base. An electroconductive film () which is used for the production of a temperature sensor film comprises a metal thin-film () on one principal surface of a resin film base (), with a chromium oxide thin-film () serving as an underlying layer interposed therebetween. A temperature sensor film is obtained by patterning the metal thin-film so as to form a thermometric resistor part and a lead part that is connected to the thermometric resistor part.

Electroconductive film and temperature sensor film

Provided is a temperature sensor film comprising a metal-thin film patterned on a resin film substrate, and having high temperature measurement accuracy. A conductive film () that is used for producing a temperature sensor film has a nickel thin film () on one principal surface of a resin film substrate (). It is preferable that the interplanar spacing of nickel (111) plane in the nickel thin-film is less than 0.2040 nm. The temperature sensor film is obtained by patterning the nickel thin film to form a temperature-measuring resistance part and a lead part connected to the temperature-measuring resistance part.

Temperature sensor film, conductive film and method for producing same

An electroconductive film () comprises a metal thin-film () on a first main surface of a flexible substrate () that includes a resin film (). The thickness of the flexible substrate is 1 mm or less. The absolute value |H−H| of the difference between the heating dimensional change rate Hof the electroconductive film and the heating dimensional change rate Hof a film obtained by removing the metal thin-film from the electroconductive film is preferably 0.10% or less. There is a tendency that undulation of a temperature sensor film after patterning of the metal thin-film is further suppressed as the value of |H−H| decreases.

The anti-reflection film includes an anti-reflection layer composed of multilayer thin-films having different refractive indexes on one principal surface of a transparent film substrate. The moisture permeability of the anti-reflection film is 15 to 1000 g/m&#xb7;24 h. The surface of the anti-reflection layer has an indentation elastic modulus of 20 to 100 GPa, and an arithmetic mean roughness Ra of 3 nm or less. The arithmetic mean roughness Ra of the surface of the anti-reflection layer is preferably 1.5 nm or less. The thin-films constituting the anti-reflection layer can be deposited by, for example, a sputtering method.
