Chip resistor and method for producing the same
Abstract:
The chip resistor (1) of the present invention includes an insulating substrate (2) in the form of a chip, a pair of terminal electrodes (3, 4) formed on both ends of the insulating substrate (2), a plurality of resistor films (5) formed on an obverse surface of the insulating substrate (2) in parallel with each other between the paired terminal electrodes (3, 4), and a cover coat formed on the obverse surface of the insulating substrate (2) to cover the resistor films (5). In the chip resistor (1), one of the terminal electrodes (3) includes individual upper electrodes (8) each formed on the obverse surface of the insulating substrate (3, 4) to be independently connected to a respective one of the resistor films (5) and a side electrode (9) formed on a side surface of the insulating substrate (2) to be connected to all the individual upper electrodes (8).
