Abstract
The present invention provides an electrically conductive polyethylene resin composition having a stable volume resistance value and in addition, a low-friction property and a wear-resistant property and a resin molding, a sliding bearing, and a sliding sheet made of the electrically conductive polyethylene resin composition. The electrically conductive polyethylene resin composition contains 100 parts by weight of ultra-high-molecular-weight polyethylene resin which cannot be injection-molded and has a weight average molecular weight of one million to four millions, 2 to 15 parts by weight of Ketjenblack, and 0.5 to 5 parts by weight of at least one powder, having an average particle size of 1 to 30 μm, which is selected from among polytetrafluoroethylene resin powder, graphite powder, and silicone resin powder.
