An integrated circuit device includes: an AFE circuit (analog front-end circuit) that receives a first signal and a second signal, carries out waveform shaping of the first signal and waveform shaping of the second signal, outputs the first signal whose waveform is shaped to a first signal line, and outputs the second signal whose waveform is shaped to a second signal line; and a time-to-digital converter that receives the first signal from the AFE circuit via the first signal line, receives the second signal from the AFE circuit via the second signal line, and converts a time difference between transition timings of the first signal and the second signal into a digital value. At least one of the first signal line and the second signal line has redundant wiring for isometric wiring.
