PROBLEM TO BE SOLVED: To provide a brush for a fuel supply device which can maintain the conditions of mounting in proper stability for a long period, without sulfurating granules by sulfuric components contained in fuel, in a brush used for the fuel supply device, for instance, in an automobile engines or the like, particularly that fix pig tail with granules to a mounting hole formed in a brush main unit. SOLUTION: This brush is characterized by providing a brush main unit 11, consisting of carbon or the like and a pig tail 12 fixedly inserted into a mounting hole 11b formed in this brush main unit, inserting this pig tail into the mounting hole, and fixedly press fitting a granule of sulfide generating energy larger than that of copper to the periphery of the pig tail in this mounting hole. Since the granules of sulfide generate energy larger than that of copper, for instance, thin powder, gold powder, nickel powder, zinc powder, etc., or these powders can be used suitably combined.
