Abstract
A strain gauge includes a substrate, a resistor formed on the substrate, and two lines. The resistor includes multiple elongated portions. Each of the lines includes a first metal layer and a second metal layer that is laminated on the first metal layer and is formed of a material having lower volume resistivity than the first metal layer. In plan view, an outer edge of the first metal layer is exposed from the second metal layer. In plan view, an end of the second metal layer on a first end side in a first direction protrudes further toward the first end side in the first direction than an end of a space that is situated between the first metal layer and an elongated portion adjacent to the first metal layer.
