Patent ID: 6943662

Claim:
A chip resistor comprising: an insulating substrate; thick-film upper surface electrodes formed at opposite ends of the top surface of the insulating substrate; a thin-film resistance made of a constituent material not reacting with NaCl, and formed so as to be extended over the upper surface of the insulating substrate and respective portions of the upper surface of the thick-film upper surface electrodes; thick-film back surface electrodes formed at spots on the back surface of the insulating substrate, corresponding to the thick-film upper surface electrodes, respectively; and thick-film side surface electrodes connecting the thick-film back surface electrodes with respective portions of the thick-film upper surface electrodes, exposed out of the thin-film resistance, respectively, wherein the thin-film resistance comprises a plurality of stacked thin films, and at least the outermost thin film layer thereof is made of a constituent material not reacting with NaCl, wherein a constituent material of a first of said thin-films in said thin film resistance is different from a constituent material of a second of said thin films.
