Abstract: An electrode unit of the invention includes: an electrode including one end and another end, the other end including a free end; and an electrode supporting portion that supports the one end of the electrode. The electrode is disposed in a second plane that is different from a first plane in which the electrode supporting portion is moved to advance or withdraw when the electrode supporting portion is moved to advance or withdraw in a direction along a longitudinal axis of the electrode supporting portion, and the electrode is supported by the electrode supporting portion via a flexed portion projecting from the first plane to the second plane.

Abstract: A treatment tool includes: a tubular portion including a tubular portion main body having a long tubular shape and an opening section provided in the tubular portion main body, the tubular portion being configured to suck a tissue piece from the opening section; a blade portion provided in a part of an opening edge in the opening section; and a non-blade portion provided in at least a part other than a region where the blade portion is provided in the opening edge, the non-blade portion being configured to slide the tissue piece. The blade portion includes an edge having a smallest sectional area in a cross section of the blade portion taken along a plane including a central axis of the tubular portion main body, and only the edge is located on an imaginary plane obtained by extending an opening surface of the opening section.
