PROBLEM TO BE SOLVED: To provide a communication system capable of performing a communication with high immediacy while transmitting information of relatively large data amount, and a communication terminal used as a slave unit in the communication system. ! SOLUTION: A slave unit 2 includes: a first communication section 21 that performs a communication with a master unit 1 using a transmission signal; a second communication section 22 that performs a communication with the master unit 1 using a superposition signal superposed with the transmission signal; and a control section 23. In a first reply band following the a transmission band in which a data not to be replied is received, the control section 23 controls the first communication section 21 not to transmit any response data and controls the second communication section 22 to transmit a superposition signal to the master unit 1. !
