Abstract
Resistance or side electrodes of a chip resistor is prevented from being lost due to chemical reaction with NaCl contained in human sweat and so on when human sweat, seawater, etc. are adhered thereto. The chip resistor comprises 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.
