<P>PROBLEM TO BE SOLVED: To provide a resistive element that reduces electromotive force for a copper electrode while maintaining low volume resistivity and a superior resistance temperature coefficient that Cu-Ni-based alloy has, a resistor, and methods of manufacturing the same. <P>SOLUTION: The resistive element is formed by stacking a first plate made of Cu-Ni-based alloy and a second plate made of Ni-Cr-based alloy, and has a diffusion layer 11c, in which the metal materials thereof are diffused, formed between the first plate 11a and second plate 11b, and the diffusion layer occupies 10% or more of the overall thickness of the resistive element. It is preferably that the plates are rolled so that one of the stacked layers has a thickness of 25 μm or more. The resistor is manufactured by forming at least one par of electrodes 12 on the resistive element 11. <P>COPYRIGHT: (C)2012,JPO&INPIT |
