A fuel hose has multilayered construction and a flexible corrugated portion with corrugation bottom portions and corrugation peak portions. The fuel hose includes a rubber layer and a resin layer that is a laminated on an inner side of the rubber layer. The resin layer has fuel permeation resistance and serves as a barrier layer. The corrugated portion satisfies a condition of H/W>=1.1 when H represents a height of the corrugation measured between an inside of the corrugation bottom portion and an inside of the corrugation peak portion thereof, and 2W represents an axial distance between an inside of the corrugation bottom portion and an inside of an adjacent corrugation bottom portion.
