<p>PURPOSE:To improve productivity by a large number of simultaneous working while realizing high density packaging by the lowering of height by executing trimming lines from both sides to a resistor formed to the surface of an insulating substrate so that adjacent trimming lines are arranged alternately from the opposite directions respectively. CONSTITUTION:A pair of internal electrodes 12 where nearer to both end sections of an insulating substrate 11 and a resistor 13, both ends of which are superposed to both internal electrodes 12, are shaped onto the surface of the insulating substrate 11, and external electrodes 14 conducting with the internal electrodes 12 are formed at both end sections of the insulating substrate 11. Trimming 3 lines 15 are executed from both sides of said resistor 13 so that adjacent trimming lines 15 are disposed alternately from the opposite direction respectively, and the surfaces of both internal electrodes 12 are coated with an insulating protective film 15 from the resistor 13. A metallic material such as Ni is used as said resistor 13, the resistor 13 is shaped rectangularly onto the insulating substrate 11 through electroless plating, etc., while the trimming lines 15 are executed zigzag from both sides by employing a laser, etc., and the width of the resistor 13 is narrowed and effective length is lengthened.</p> |
