PROBLEM TO BE SOLVED: To provide a balloon catheter being usable for an intravenous chemical ablation treatment for the primary aldosteronism and, in particular, capable of treating only the tumor of a secondary vein whose abnormality is revealed.SOLUTION: A balloon catheter for use in an intravenous-approach chemical ablation treatment of the adrenal gland tumor, includes an inner tube 10, an outer tube 30, a balloon 50, and a connector 70 having a guide wire port 71 and an expansion port 73. The outer tube 30 has a proximal-side high hardness portion 301 having the hardness of 72D or more, and a distal-side low hardness portion 302 having the hardness of 25D or more and less than 72D. The outside diameter of the outer tube 30 is 0.70-1.20 mm and the length of the balloon 50 is 0.5-5 mm.SELECTED DRAWING: Figure 1A
