Abstract
There is provided a multilayer resin tube having a plurality of thermoplastic resin layers, wherein an intermediate layer of the resin layers comprises an acid modified resin modified by the introduction of a functional group, and at least one layer is a barrier layer comprising an aromatic polyamide, for example, PA9T. The multilayer resin tube has good low-permeability attained with the use of an inexpensive resin, without using an expensive highly-functional resin such as a fluororesin.
