Hollow structure for fuel

A hollow structure for fuel, comprising a polyamide resin layer (A), a polyamide resin layer (B), a polyamide resin layer (C), and a conductive layer (D) in this order from an outside,

• wherein the polyamide resin layer (A) comprises a polyamide resin (a), 90 mol % or more of all structural units of the polyamide resin (a) being one or more of:
• a structural unit derived from a lactam having from 10 to 12 carbon atoms;
• a structural unit derived from an aminocarboxylic acid having from 10 to 12 carbon atoms;
• a structural unit derived from an aliphatic dicarboxylic acid having from 6 to 12 carbon atoms;
• and a structural unit derived from an aliphatic diamine having from 6 to 12 carbon atoms,
• wherein the polyamide resin layer (B) comprises a polyolefin, a polyamide resin (b1), and a polyamide resin (b2);
• a content of the polyolefin is from 5 to 40 mass % of the polyamide resin layer (B);
• a mass ratio (b1/b2) between a content of the polyamide resin (b1) and a content of the polyamide resin (b2) is from 55/45 to 95/5, the polyamide resin (b1) comprising:
• a diamine-derived structural unit containing 70 mol % or more of a structural unit derived from metaxylylenediamine;
• and a dicarboxylic acid-derived structural unit containing 70 mol % or more of a structural unit derived from an aliphatic dicarboxylic acid having from 4 to 8 carbon atoms, the polyamide resin (b2) comprising:
• a diamine-derived structural unit containing 70 mol % or more of a structural unit derived from xylylenediamine;
• and a dicarboxylic acid-derived structural unit containing 70 mol % or more of a structural unit derived from an aliphatic dicarboxylic acid having from 9 to 12 carbon atoms,
• wherein the polyamide resin layer (C) comprises a polyamide resin (c), 90 mol % or more of all structural units of the polyamide resin (c) being one or more of:
• a structural unit derived from a lactam having from 10 to 12 carbon atoms;
• a structural unit derived from an aminocarboxylic acid having from 10 to 12 carbon atoms;
• a structural unit derived from an aliphatic dicarboxylic acid having from 6 to 12 carbon atoms;
• and a structural unit derived from an aliphatic diamine having from 6 to 12 carbon atoms, and
• wherein the conductive layer (D) comprises a fluororesin and a conductive substance.
