Abstract
A strain gauge includes a flexible substrate, resistors each formed of a film that includes Cr, CrN, and CrN, and a functional layer formed of a metal, an alloy, or a metal compound, the functional layer being in a lower surface of the resistors. The resistors include a first resistor formed on or above a predetermined surface of the substrate; a second resistor of which a grid direction faces a different direction from the first resistor, the second resistor formed on or above the predetermined surface of the substrate or a surface parallel to the predetermined surface; and a third resistor formed on or above a surface adjacent to the predetermined surface of the substrate.
