Abstract: The present invention relates to a tube with coupling according to which liquid leakage and the like can be suppressed as much as possible when couplings are connected. A tube with coupling (10) according to the present invention is a tube with coupling (10) obtained by forming a coupling (30) on a leading end portion (22) of a tube (20) through injection molding, and the leading end portion (22) of the tube (20) is arranged at a position set back from a leading end portion (32) of the coupling (30), at least a portion of the leading end portion (22) of the tube (20) being covered by the coupling (30). It is desirable that a flange (36) is provided so as to protrude outward at a position set back from the leading end portion (32) of the coupling (30) and the leading end portion (22) of the tube (20) is arranged at a position set further back from the flange (36).
