The multilayered pellets each are composed of at least two resin layers and include a resin layer A whose main component is EVOH and a resin layer B whose main component is a polyamide resin. In the multilayered pellets, at least 70 mol % of all the terminals of the polyamide resin are blocked by units each containing an imide structure.
