Provided is a multilayer vessel excellent in gas barrier performance and transparency and its application. The multilayer vessel contains a layer (X) that contains at least one type of polyolefin resin as the major ingredient； and a layer (Y) that contains a polyamide resin (A) as the major ingredient, the polyamide resin (A) being composed of a structural unit derived from diamine, and a structural unit derived from dicarboxylic acid, 70 mol% or more of the structural unit derived from diamine being derived from metaxylylenediamine, meanwhile 30 to 60 mol% of the structural unit derived from dicarboxylic acid being derived from straight chain aliphatic ±,É-dicarboxylic acid having 4 to 20 carbon atoms, and 70 to 40 mol% being derived from isophthalic acid.
