摘要: A resin-made fuel inlet pipe that has a light weight, excellent impact resistance, and causes no fuel leakage includes at least one resin layer comprising a resin composition containing (A) a high-density polyethylene (HDPE) or a linear short-chain branched polyethylene; (B) a polyethylene polymerized with a metallocene-based catalyst; and (C) a carbon black. A weight mixing ratio ((A)/(B)) is in a range of from 10/90 to 90/10; a content of component (C) is in a range of from 0.1 to 5 parts by weight with respect to 100 parts by weight of a total of components (A) and (B); a tissue (Y) comprising component (B) is inserted between linear crystalline tissues (X) comprising component (A) to expand an interval between the tissues (X); and component (C) is dispersed in the tissue (Y).
