A strain gauge includes a flexible substrate, a resistor formed of material containing at least one from among chromium and nickel, on or above the substrate, and a pair of electrodes electrically connected to the resistor. Each electrode includes a plurality of first patterns that are juxtaposed at predetermined intervals and that are electrically connected to each other. A plurality of second patterns of which longitudinal directions are toward a same direction as a longitudinal direction of each of the first patterns are disposed between opposing electrodes.

Strain gauge

A strain gauge includes a flexible substrate; and resistors each formed of a Cr composite film. The resistors include a first resistor and a second resistor that are formed on one side of the substrate, and include a third resistor and a fourth resistor that are formed on another side of the substrate. The first resistor, the second resistor, the third resistor, and the fourth resistor constitute a Wheatstone bridge circuit.

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.

Strain gauge with improved distortion of measured object

A strain gauge includes a flexible substrate, and resistors each formed of a Cr composite film. The resistors include a first resistor formed on one side of the substrate and includes a second resistor formed on another side of the substrate. The first resistor and the second resistor are arranged such that grid directions of the first resistor and the second resistor intersect in a plan view.
