Abstract: A medical gripping tool includes: an elongated insertion section; a gripping section; an operating unit; and a wire that transmits, to the gripping section, a driving force input to the operating unit. The gripping section includes a pair of gripping pieces supported so as to be relatively swivelable. The pair of gripping pieces include a pair of first gripping sections, and a pair of second gripping sections that are disposed at positions farther away from a swiveling axis than the pair of first gripping sections are. In a state in which the pair of gripping pieces are closed by the driving force transmitted by the wire, opposed surfaces of the pair of first gripping sections are disposed with a first distance therebetween, and opposed surfaces of the pair of second gripping sections are disposed with a second distance, which is longer than the first distance, therebetween.
