Abstract: A liquid feed tube for feeding a liquid from a liquid tank disposed on a liquid jetting device body side to a jetting head mounted on a reciprocating carriage, including: a long elastic member and a film member connected in an airtight state to the elastic member along a longitudinal direction of the elastic member; and a space part formed by the elastic member and the film member and used as a liquid feed passage, wherein the elastic member is made of a specific resin composition. Thus, the bending rigidity of the liquid feed tube can be lowered, and the resistance to moisture permeability and the gas barrier property thereof can be realized at low cost.
