Abstract
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 (101) which is used for the production of a temperature sensor film comprises a metal thin-film (10) on one principal surface of a resin film base (50), with a chromium oxide thin-film (21) 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.
Claims12
An electroconductive film for a temperature sensor,
- the electroconductive film comprising:
- a resin film base;
- a metal thin-film disposed on one principal surface of the resin film;
- and an underlying layer interposed between the resin film and the metal thin-film, wherein
- the underlying layer includes a chromium oxide thin-film and a silicon-based thin-film in this order from a side of the resin film base.
A temperature sensor film comprising:
- a resin film base;
- an underlying layer formed on one principal surface of the resin film base;
- and a metal thin-film patterned on the underlying layer, wherein
- the metal thin-film is patterned to form a thermometric resistor part patterned into a thin wire and used for measuring a temperature and a lead part connected to the thermometric resistor part and patterned to have a larger wiring width than that of the thermometric resistor part, and
- the underlying layer includes a chromium oxide thin-film and a silicon-based thin-film in this order from a side of the resin film base.
