An electrosurgical instrument having a distal end and a gripping device which is arranged at the distal end in the longitudinal direction and which includes at least a clamping jaw portion and a coagulation jaw portion. The coagulation jaw portion has a plurality of electrically separated coagulation electrodes which are substantially immovable relative to each other. At least one of the jaw portions is movable from an open position into a closed clamping position, wherein the jaw portions at least portion-wise engage into each other in the clamping position and are of such a configuration that the tissue can be clamped between the jaw portions substantially in a half-wave shape. The coagulation jaw portion has at least two electrode arrangements which are arranged at different sides and have respective electrically separated coagulation electrodes, by means of which the tissue is coagulatable in two substantially mutually separated coagulation regions.
