Claim 25:
26. The method for manufacturing a multilayer vessel of claim 11, the method comprising:
conducting direct blow molding, using
a material that composes the layer (X) containing the cycloolefin-based polymer (B) as a major ingredient;
a material that composes the adhesive layer; and,
a material that composes the layer (Y) containing the polyamide resin (A) as the major ingredient,

the polyamide resin (A) is 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 is derived from metaxylylenediamine, and
30 to 60 mol % of the structural unit derived from dicarboxylic acid is derived from a straight chain aliphatic α,ω-dicarboxylic acid having 4 to 20 carbon atoms, and 70 to 40 mol % is derived from isophthalic acid.
