Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a balloon catheter balanced in extrudability, follow-up characteristic and passability. SOLUTION: The over-the-wire type balloon catheter including a guide wire has an inner tube 28 made of polyethylene and an outer tube 34 having an outer tube proximal part 56 having relatively high rigidity, a shaft central part having relatively low rigidity and a convergent outer tube distal end 68 having the lowest rigidity. An dilatable balloon 24 is joined to the inner tube 28 and the outer tube distal end 62. The extraction of the guide wire from the guide wire lumen 54 or the insertion thereof into the guide wire lumen 54 at both ends of the catheter are made possible.
