An operative instrument for endoscopic surgery which can be used in combination with a normal, straight trocar. The operative instrument for endoscopic surgery includes a jacket tube (11), which is formed from an elastic tubular member to normally maintains a curved shape and can be elastically deformed to be insertable into a straight, cylindrical trocar (1), a manipulating shaft (27), which is elastic, has a distal end operative member (24) connected to the distal end thereof for performing a treatment within the body, and is passed through the jacket tube (11), and a manipulating part (30), which is connected to the proximal side of the jacket tube (11) for manipulating the distal end operative member (24) via manipulating shaft (27).
