RESISTOR PASTE AND METHOD OF MANUFACTURING THE SAME, AND RESISTOR AND USE APPLICATION FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a resistor paste capable of suppressing variation in resistance value even at a low or middle resistance of a volume resistivity of 200μΩcm (having a surface resistance of 200 mΩ/SQ. at a film thickness of 10μm) or more.SOLUTION: A resistor paste includes: a conductive component formed of a metal containing copper and nickel; a resistance adjustment component formed of a non-conductive inorganic particle not melted nor thermally decomposed at a firing temperature; an inorganic binder formed of a low-melting point glass particle having a softening point lower than the firing temperature; and an organic vehicle for dispersing these components. In the resistor paste, at least a part the conductive component covers at least a part of the resistance adjustment component to form a composite particle in which a surface of at least a part of the non-conductive inorganic particle is covered with a conductive layer. A thickness of the conductive layer may be about 0.05-5μm. The conductive layer may be formed by electroless plating. The conductive component may be further contain a metal particle.
