The narrow width part is configured to be disposed at a position where the second grasping member does not easily suffer a stress due to ultrasonic vibration when the living tissue is grasped between the second grasping member and the first grasping member, and to make a distance between the mutually opposed surfaces of the first electrode portion and the second electrode portion narrower than a distance at other positions. | 2009-10-01 |
