In the balloon catheter (1), the inner tube (3), the outer tube (2), the distal end portion (42) are fixed to the inner tube (3) and the rear end portion (44) is fixed to the outer tube And a balloon (4). The balloon includes an inflatable portion (41), a rear end side tubular portion (43) positioned between the inflatable portion and the rear end portion (44) and extending by a predetermined length and uninflatable. The balloon catheter (1) has a three-point bending load value A1 per unit deflection in the inflatable portion of the balloon and a unit in a fixed part between the rear end of the rear end side cylindrical portion of the balloon and the distal end portion of the outer tube The three-point bending load value A2 per deflection is A1
