Abstract
According to the present disclosure, a strain gauge includes: a flexible substrate; a resistor made from a film containing Cr, CrN, and Cr2N, on one surface of the substrate; and a resin barrier layer covering the resistor, and, in this strain gauge, in the barrier layer, a ratio of a moisture permeability (g/m2/24 h) to a thickness (mm) is 5:1 or greater, and the thickness of the barrier layer is 100 μm or more and 3 mm or less.
