The described technology relates to a suture device for a surgical operation that makes it easy to suture a wound or an incision. A suture device for a surgical operation includes: a suture needle that is curved with a needle eye at one end to be threaded with a first suture, and swings at an incision; a holder that supplies a second suture, rotates in one direction, and stops, corresponding to the swing of the suture needle to weave the first suture and the second suture and suture the incision; a first rotary member that is connected to a first shaft of the suture needle; a second rotary member that is connected to a second shaft of the holder; and a third rotary member that is provided between the first rotary member and the second rotary member, and connected to a third shaft to transmit torque to the second rotary member.
