Provided is a hollow structure for fuel, in which a conductive layer containing a fluororesin is used, that is excellent in fuel barrier properties and low-temperature impact resistance, and further is excellent in interlayer adhesion. [0002] The hollow structure for fuel includes 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. The polyamide resin layer (A) contains a polyamide resin (a). The polyamide resin layer (B) contains a polyolefin, a polyamide resin (b1) containing a structural unit derived from metaxylylenediamine and a structural unit derived from an aliphatic dicarboxylic acid having from 4 to 8 carbon atoms, and a polyamide resin (b2) containing a structural unit derived from xylylenediamine and a structural unit derived from an aliphatic dicarboxylic acid having from 9 to 12 carbon atoms. The polyamide resin layer (C) contains a polyamide resin (c). The conductive layer (D) contains a fluororesin and a conductive substance.
