PROBLEM TO BE SOLVED: To provide a fuel hose superior in low permeability to fuel for an automobile, and superior even in sour resistance. SOLUTION: An intermediate layer 2 is formed on an outer peripheral surface of an inner layer 1, and an outer layer 3 is also formed and constituted on its outer peripheral surface. This invention is maximally characterized in that the inner layer 1 is formed by using polybutylene naphthalate thermoplastic elastomer having a dimer acid component. The polybutylene naphthalate thermoplastic elastomer (PBN type TPE including the dimer acid component) having the dimer acid component is used as a material for the inner layer 1.
