Provided is an integrated depth-of-anesthesia/cerebral-oxygen-saturation detection sensor. Particularly, thedepth-of-anesthesia/cerebral-oxygen-saturation detection sensor includes a strap and a sensing unit that is arranged on the strap, and sensing unit includes a depth-of-anesthesia sensor and a cerebral oxygen saturation sensor that are arranged on the same plane. Therefore, it is possible to simultaneously measure a depth of anesthesia and cerebral oxygen saturation with a single detection sensor, so that it is possible to reduce cost.
