A balloon-equipped ablation catheter used to efficiently cauterize a cardiac wall. A guide wire for a balloon-equipped ablation catheter, provided with a bending section, wherein the bending section has a bending region provided in that region of the guide wire which has a length of at least 20 mm in the longitudinal direction of the guide wire and having bending rigidity in the range of 570 to 3740 N?mm2, the guide wire bending angle which is the angle formed between the tangent line at the start point of the bending region and the tangent line at the end point of the bending region, said tangent lines intersecting each other, and measured in the direction of the bend from the tangent line at the start point of the bending region is in the range of 45 to 180 degrees, and the balloon bending angle which is the angle measured relative to the longitudinal direction when the guide wire is inserted in a lumen, which communicates from the distal end to the proximal end in the longitudinal direction of a shaft for the balloon-equipped ablation catheter, and the bending region is located right below the balloon is in the range of 30 to 90 degrees. |
