This is to introduce a strain sensor of high quality and excellent durability. This strain sensor is composed of a basic metal body, a crystallized glass layer formed over the surface of the basic metal body, and a resistance element that changes its resistance value by strain changes and is built on the glass layer surface. By this structure, where the crystallized glass layer fired at a high temperature is employed, both of the composition, the basic metal body and the glass layer, are fused with each other at the boundary plane, making their adhesion very strong. No peeling between the basic metal body and the glass layer will take place even under the severe environmental conditions such as high temperature and heavy load.
