PROBLEM TO BE SOLVED: To provide a ternary detection circuit capable of achieving precise ternary level detection relating to an input signal by a low power supply voltage configuration, capable of suppressing power consumption by reducing the whole circuit scale, and capable of easily responding to a mobile device which is advanced in miniaturization by low power consumption. SOLUTION: Circuit formation is made to be enabled by a CMOS process. Ternary level detection can be enabled by a state of output signals from output terminals 4, 5 relating to an input signal to an input terminal 3 even reducing the whole circuit area by miniaturizing each of transistor elements configuring the circuit, and even by a low power supply voltage by further reducing power consumption to be needed for a circuit operation.
