PROBLEM TO BE SOLVED: To provide a method of manufacturing an elastic tube equipped with a connector without deformation of the elastic tube within the connector. SOLUTION: The manufacturing method of the elastic tube comprises a clamping procedure 400 of attaching a mold 410 having a molding face 411 surrounding one-end's of the ink supply tubes 210 at specified intervals and a tight adhesion face 412 surrounding the ink supply tubes 210 without clearances, to ink supply tubes 210, in a part of the portion into which the insertion portion 422 of a core pin 420 is inserted, so as to form a molding space of geometry complementary to the connector 214. In the clamping procedure 400, the molding space formed so as to face the surface area of the ink supply tubes 210 adjacent to the tight adhesion face 412 becomes narrower in the cross-section perpendicular to the flowing direction in the molding space as a material resin charged into the mold 410 through a charging procedure approaches the end in the flowing direction along the ink supply tubes 210.
