<p><P>PROBLEM TO BE SOLVED: To provide a resistive element whose resistance value can be adjusted to a set resistance value by trimming, even if the resistance value thereof becomes higher than a set value due to the blur upon printing and/or the chip of a patten when a resistor is formed by printing etc.; and to provide a wiring circuit board with a built-in resistive element. <P>SOLUTION: The resistive element and the wiring circuit board 100 with the built-in resistive element is manufactured by forming wiring layers 21 on an insulating layer 11, electrodes 21a and a wiring layer 22 at the tips of the wiring layers 21, and a noble metal coats 31 consisting of a silver plating layer on the electrodes 21a; and forming a main resistor 41 and an auxiliary resistor 42 arranged in parallel by screen printing. Further, the resistive element and the wiring circuit board with the built-in resistive element wherein the adjusted resistance value thereof can be obtained by adjusting the resistance value of the auxiliary resistor 42 according to laser trimming etc. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
