description A catheter tube unit 2a of the present invention is housed in a catheter tube 2 of an electrode catheter 1, and used for the catheter tube whose distal end is made bendable and stretchable through a wire 5 fixed to the distal end, when the wire is manipulated from a base end side. The catheter tube unit includes the wire, a long and integrated structure 10 including at least a core tube 6 through which the wire is inserted, a plurality of lead wires 7, 7 . . . arranged around an outer circumference of the core tube and connected to electrodes 4, 4 . . . , and a sheath 8 that envelopes the plurality of lead wires overall at least over the exterior, and an exterior tube 11 composed of an extrusion-molded article arranged over the outer circumferential face of the structure, while placing the structure as a core.
