Provided is a bipolar electrosurgical device that makes it possible to inexpensively achieve a configuration in which high-frequency energy is applied to living tissue in a uniform manner. The bipolar electrosurgical device (100) comprises a first gripping section (121) and a second gripping section (111) for gripping living tissue and serves to fuse living tissue that is gripped by the first gripping section (121) and the second gripping section (111). The bipolar electrosurgical device (100) is provided with: a planar first electrode that is arranged along the gripping surface of the first gripping section (121) a second electrode that is arranged along the gripping surface of the second gripping section (111) and that comprises a plurality of electrically isolated metal members that are arranged in an energizable state along the gripping surface and the rear surface thereof and a sliding plate that slides while in contact with one part of the surface of the second electrode that is the opposite surface of the surface that faces the first electrode. The bipolar electrosurgical device (100) is characterized in that living tissue is fused at each position to which the sliding plate moves by energizing the interval between the planar first electrode and the planar second electrode.Linvention concerne un dispositif électrochirurgical bipolaire qui permet dobtenir une configuration peu coûteuse dans laquelle de lénergie à haute fréquence est appliquée à des tissus vivants de manière uniforme.
