An electrosurgical instrument includes a jaw part with instrument branches which are movable towards each other. One or more electrode surfaces are arranged on mutually facing sides of the branches. Relative movement of the instrument branches can be limited by at least one proximal spacer acting on proximal end portions of the instrument branches. At least one medial spacer acts on a medial portion, and at least one distal spacer acts on distal end portions of the instrument branches. The proximal and/or the distal spacer are made of electrically non-conductive material, and the at least one medial spacer includes at least one electrode made of an electrically conductive material and connected electrically conductively to the electrode. The at least one medial spacer interacts with a local insulation component made of a non-conductive material, which insulation component is arranged in an electrically insulating manner on at least one opposite electrode.
