Resistive paste and mechanical amount sensor employing it



PROBLEM TO BE SOLVED: To obtain a resistor element having high strain sensitivity by coating the surface of an insulating substrate with a resistive paste comprising a composite oxide containing copper and glass frit and then drying and firing it. SOLUTION: The mechanical amount sensor comprises an insulating substrate, a strain-sensitive resistor element 4, and a pair of electrodes 3 for detecting variation in the electrical resistance of the strain-sensitive resistor element 4. The resistor element 4 is formed by coating the surface of the insulating substrate with a resistive paste comprising a composite oxide containing copper, glass frit, an organic vehicle and a diluent and then drying and firing it. The organic vehicle and the diluent are dispersed at the time of drying and tiring and an excellent mechanical amount sensor is obtained. Preferably, the insulating substrate comprises a metal substrate 1 coated with a crystallized glass layer 2. The metal substrate 1 is coated with the crystallized glass layer 2 by printing, spraying, powder electrostatic painting, electrophoresis, etc.
