Abstract
A functional film includes a strain resistance film provided on one principal surface of a flexible insulating base. The strain resistance film is a chromium nitride thin-film having a thickness of 150 nm or less. In an X-ray diffraction chart with a CuKα ray as an X-ray source, the strain resistance film has an intensity ratio I/Iof 0.001 or more, where the intensity ratio I/Iis a ratio of the intensity Iof the second peak in a range in which 2θ is 60° to 65° to the intensity Iof the first peak in a range in which 2θ is 43° to 45°. The strain resistance film is less liable to crack due to bending, and has a high gauge factor. The functional film is suitably used for a strain sensor.
