An ECL terminating circuit, in which it is prevented that the amplitude of an output signal from an ECL outputting circuit or a PECL outputting circuit is lowered caused by that the supply voltage for the circuit has been lowered, and also it is prevented that the waveform of the output signal is deteriorated caused by that the distance of a transmission line where the output signal being high speed is transmitted is made to be long, is provided. The ECL terminating circuit consists of a PECL outputting circuit, a resistor, a transmission line, a load circuit, and a terminal element. And the terminal element is connected to the resistor in series and the resistance value of the terminal element is about 0 OMEGA at a direct current (DC), but is made to be large at an alternating current (AC).
