摘要： A time measurement device measures a time interval between input timings of first and second pulsed target signals. The device includes: a processor; a number-of-periods detector that detects, by using a clock signal with a predetermined clock frequency and a predetermined clock period, the time interval in units of the clock period; and a phase detection unit including a band-pass filter. The band-pass filter receives at least one of the first and second target signals as a filtering target signal and extracts a signal component of the clock frequency from the filtering target signal. The phase detection unit detects a phase difference between the extracted signal and the clock signal. The processor derives, by using a result detected by the number-of-periods detector and the detected phase difference, the time interval at a resolution finer than the clock period.
