Abstract
A strain sensor comprising a metal substrate, a first electrode provided on the metal substrate, a glass layer formed on the first electrode, and a second electrode and a strain detecting resistor provided on the glass layer. In the strain sensor, the insulation resistance between the metal substrate and the second electrode has been raised, and the reliability is high. It can be implemented at low cost.
