Abstract
The invention presents a strain sensor includes a substrate, a crystallized glass laminated on the substrate, a strain sensitive resistor laminated on the crystallized glass, in which the crystallized glass is formed by baking a plurality of types of crystallized glass powder having different thermomechanical constants. As a result, the fluctuation of sensor characteristic is decreased, and the cost is lowered.
