Abstract
The present invention is directed towards a resistor which has higher load-, surge-, and pulse-resistant characteristics and is capable of having a resistance adjusted at a higher rate of precision. A pair of electrodes 12 and a main resistance path 13 between the two electrodes 12 are mounted on a substrate 11. The main resistance path 13 is joined to a set of first rungs 14 which extend parallel to the main resistance path 13 and are joined with two first connecting paths 15 to form a first ladder-like resistance path for rough adjustment of the resistance which is connected to a part of the main resistance path 13. Also, a second ladder-like resistance path for fine adjustment of the resistance which comprises a set of second rungs 16 extending vertically from the main resistance path 13 and two second connecting paths 17 joining the second rungs 16 together is formed and connected to a part of the main resistance path 13. A combination of the two ladder-like resistance paths of a resistive body for rough and fine adjustments of the resistance permits a desired resistance to be set at a higher precision thus providing the higher load-, surge-, and pulse-resistant characteristics…
