A bipolar treatment device includes a probe, the probe including a distal surface portion in which an outer peripheral distal end of an outer peripheral portion is an outer edge, and a path defining surface defining a suction path inside the probe along the longitudinal axis to the distal surface portion. The probe includes a first protrusion protruding the outer peripheral distal end of the outer peripheral portion toward a first perpendicular direction, that is perpendicular to the longitudinal axis and perpendicular to open/close directions of the jaw. The distal surface portion of the probe includes an inclined plane in which it goes toward a distal direction side as it goes from the first perpendicular direction toward a second perpendicular direction, that is opposite to the first perpendicular direction, the inclined plane extending from a first end position to a second end position, the first end position being located to the first perpendicular direction side of a first root position of the first protrusion, and the second end position being located to the second perpendicular direction side of the suction path. |
