<P>PROBLEM TO BE SOLVED: To provide a trimming method of a chip resistor capable of obtaining a precise resistance value. <P>SOLUTION: The trimming method of a chip resistor includes the steps of: forming a resistor 13 electrically connected to a pair of upper surface electrodes 12 formed at both ends of the upper face of an insulating substrate 11; and forming a trimming groove 14 by cutting the resistor 13 using a laser from one side face 13a of the resistor 13 toward the center thereof while measuring the resistance value of the resistor 13 by bringing a voltage measuring probe 15 and a current measuring probe 16 with the upper surfaces of the pair of upper surface electrodes 12. Contact points 15a of the voltage measuring probe 15 are positioned at a point closer to the resistor 13 than contact points 16a of the current measuring probe 16. The contact points 15a of the voltage measuring probe 15 are positioned at a point closer to the other side face 13b of the resistor 13 than the contact points 16a of the current measuring probe 16. <P>COPYRIGHT: (C)2013,JPO&INPIT |
