PROBLEM TO BE SOLVED: To provide a time measuring device capable of precisely measuring the time between the edges of signals. SOLUTION: This time measuring device 100 is provided with a first selection section 116 selecting a received signal or its inverted signal as a first signal, a first driver 120 outputting the first signal, a second selection section 118 selecting the signal or the inverted signal as a second signal, a second driver 122 outputting the second signal, and a time measuring section 130 measuring the time between the edges of signals based on the edges of the wave-forms of the first signal and the second signal.
