Abstract: A strain gauge includes a flexible substrate and a resistor formed of material including at least one of chromium or nickel, the resistor being situated above the substrate. The strain gauge includes a functional layer formed of an insulating material that has a higher thermal conductivity than the resistor, the functional layer being situated between the substrate and the resistor. The resistor includes multiple resistive patterns that are juxtaposed. The resistor includes folded portions each of which connects end portions of resistive portions that are next to each other. A first metallic layer formed of a material that has a higher thermal conductivity than the resistor is laminated on the folded portions.

Abstract: A strain gauge includes a flexible substrate, at least one resistor formed on or above the substrate, and a pair of electrodes formed on or above the substrate, electrodes being electrically coupled to the resistor via lines, respectively.
