A loop-back test is to be executed during wireless transmission in a circuit that performs wireless communication. A transmission circuit modulates a transmission information signal and supplies the transmission information signal, as a transmission signal, to an antenna. A loop-back test signal generation circuit modulates a predetermined signal to be modulated and supplies the predetermined signal to be modulated as a loop-back test signal. A selection unit selects one of a reception signal from the antenna or the loop-back test signal, and supplies the selected signal as a signal to be demodulated. A reception circuit demodulates the signal to be demodulated and acquires a reception information signal. A test circuit compares the reception information signal and the predetermined signal to be modulated.
