PROBLEM TO BE SOLVED: To provide an ink feed tube which can shut the oxygen entering from outside thereby to prevent remaining ink from being changed in quality for a long time, and has superior flexibility even under low temperatures and high durability to repeated bendings. SOLUTION: An ink feed tube 1 is of a multi-layer construction. Polyolefin of a flexural modulus of elasticity of not larger than 8000kg/cm<2> is arranged at an inner layer 2 in touch with ink. A resin of a blend of an ethylene-vinyl acetate copolymer saponification substance containing ethylene by 25-50mol% and having a degree of saponification of 96% or higher, and a compatible elastomer with good low temperature characteristics is arranged at an outer layer 3. |
