Patent ID: 7397340

Claim:
A method of manufacturing a load sensor, comprising: forming a glass layer on a substrate made of metal; providing glass paste; forming an adjusting layer by applying the glass paste onto the glass layer and firing the applied glass paste; forming a plurality of wirings on the adjusting layer; and forming a strain-sensitive resistor element connected among the plurality of wirings by applying resistor element paste onto the adjusting layer and firing the resistor element paste, wherein a thermal expansion coefficient of the adjusting layer is closer to a thermal expansion coefficient of the strain-sensitive resistor element than to a thermal expansion coefficient of the glass layer, wherein said providing the glass paste comprises: dispersing ceramic powder in solvent and binder as to have a viscosity which is not smaller than 0.01 poises and is smaller than 100 poises, and dispersing glass powder in the solvent and the binder including the ceramic powder dispersed therein to have a viscosity which is not smaller than 100 poises and is smaller than 10,000 poises.
