<p>PROBLEM TO BE SOLVED: To reduce the mis-cutting of a trimmer resistor having a neck part to be electrically cut of by applying specified cutting voltage for adjusting the resistance. SOLUTION: A trimmer resistor 1 has a means A for applying a cutting voltage to only a neck part 4 of the resistor 1 at cutting of this part 4. This means A comprise a first diode 5a inserted between the vicinity of the neck part 5a and pad 3 so as to go around part other than the neck part 4, and second diode 5b inserted between the vicinity of the neck part 4 and wiring 2.</p> |
