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.

Abstract: A tip seal 1 for a scroll compressor capable of reducing a frictional force between scroll members and the tip seal where the tip seal 1 has a spiral shape for sealing a compression chamber formed between a fixed scroll and a movable scroll in a scroll compressor provided with the fixed scroll. The movable scroll having a plurality of concave parts 4 being formed by partially notching a sliding surface 5 on the scroll members, the concave parts 4 being arranged on at least one of a spiral inner peripheral surface 1b or a spiral outer peripheral surface 1a. Each of the concave parts 4 being open to the inner peripheral surface 1b or the outer peripheral surface 1a.
