Abstract: An ultrasonic treatment instrument includes a vibration transmitting member transmitting ultrasonic vibration toward a first gripper and formed as one piece, and a second gripper movable between a spaced position where the second gripper is spaced apart from the first gripper and a closed position where the second gripper is put in close to the first gripper. The ultrasonic treatment instrument includes an interlocking actuator increasing, by moving the first gripper in interlock with a movement of the second gripper to the spaced position, a spacing distance between the first gripper and the second gripper in accordance with a movement of the first gripper.
