An ultrasound endoscope system includes: an ultrasound endoscope including an identification section that stores endoscope state information； a video processor including a first read-out section that reads out the endoscope state information in the identification section in the ultrasound endoscope； an ultrasound observation apparatus including a second read-out section that reads out endoscope state information obtained by a communication section for observation apparatus； and a control section that compares the endoscope state information obtained by the first read-out section in the video processor and the endoscope state information obtained by the second read-out section in the ultrasound observation apparatus, and performs control for establishing wireless communication between the ultrasound endoscope and the ultrasound observation apparatus only when the endoscope state information obtained by the first read-out section and the endoscope state information obtained by the second read-out section match with each other.
