PROBLEM TO BE SOLVED: To provide a laminated structure excellent in low temperature impact resistance, chemical impermeability, interlaminar adhesiveness and chemical resistance. SOLUTION: The laminated structure is composed of at least two layers, that is, a layer (a) comprising an aliphatic polyamide (A) and a layer (b) comprising a half-aromatic polyamide (B) comprising a diamine unit containing 60 mol% or above of a xylylenediamine and/or a naphthalenedimethylamine with respect to the whole diamine unit and a dicarboxylic acid unit containing 60 mol% or above of a 8-13C aliphatic dicarboxylic acid unit with respect to the whole dicarboxylic acid unit.
