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.
