PROBLEM TO BE SOLVED: To provide a multilayer structure excellent in flexibility and fuel barrier property.SOLUTION: There is provided a multilayer structure having a polyolefin layer (A) and a polyether-polyamide layer (B), wherein the polyether-polyamide (B) contains a polyether-polyamide (b) containing a constitutional unit in which a diamine constitutional unit is derived from a polyether diamine compound (b-1) represented by the following general formula (1) and a xylylene diamine (b-1) and a constitutional unit in which a dicarboxylic acid constitutional unit is derived from an α,ω-straight-chain aliphatic dicarboxylic acid (b-3) having 4 to 20 carbon atoms. (wherein, x+z represents 1 to 60; y represents 1 to 50; -OR- each independently represents -OCHCHCH-, -OCH(CH)CH- or -OCHCH(CH)-; and -OR- represents -OCHCHCHCH- or -OCHCH-.) |
