A clip treatment tool includes a clip body that has two clip-pieces, the two clip-pieces each having a body-portion and an arm-portion, the body-portion having a fixing-hole formed on a proximal end side and a movement hole formed on a distal end side relative to the fixing-hole, the movement hole extending so as to be inclined from a side part in a width direction of the body-portion on the proximal end side toward a middle in the width direction of the body-portion on the distal end side； a container tube that contains the body-portions of the two clip-pieces therein； a stopper that extends through the fixing-holes of the two clip-pieces and that is attached to the clip body； and a fixing pin that extends through the movement holes of the two clip-pieces and whose both end portions are fixed to positions in the container tube that face each other.
