Abstract: A needle holder includes a sheath, a grasper capable of grasping a target object, an operation portion capable of opening and closing the grasper, and an operation wire. The operation portion includes a main body, a slider, and an elastic member that is elastically deformable depending on an opening and closing position of the grasper. The slider is connected to the grasper via the operation wire. The grasper can release grasping of the target object and can grasp the target object with a first grasping force in response to an operation of moving the slider against a restoring force of the elastic member. The grasper can grasp the target object with a second grasping force smaller than the first grasping force when the restoring force of the elastic member and tension of the operation wire are balanced.
