Highly safe scissors for an endoscope is configured in such a manner that the angle of opening of the scissor elements can be restricted and that excessive opening and closure of the scissor elements are suppressed.Scissors (1) for an endoscope includes: a treatment section (5) provided with a pair of scissor elements (10, 11) which are pivotably supported by a pivoting shaft (support pin (13)) and are pivotally displaced between an open position and a closed position an operation wire (3) connected to the treatment section (5) and an operation section for displacing the scissor elements (10, 11) between the open position and the closed position by advancing and retracting the operation wire (3). A stopper (14) is provided to the treatment section (5). In the open position, the stopper (14) restricts the relative movement between the pair of scissor elements (10, 11) in the opening direction, and in the closed position, the stopper (14) restricts the relative movement between the pair of scissor elements (10, 11) in the closing direction.
