An imaging device includes: an imaging unit； a drive signal generation unit configured to generate and output a plurality of drive signals for driving the imaging unit； a differential converter configured to convert one of the plurality of drive signals into a differential signal； a pair of signal lines configured to transmit the differential signal and configured such that impedance matching does not occur at a terminal of one of the pair of signal lines； and an adjustment unit configured to send a detecting signal to the one of the pair of signal lines, and to adjust characteristics of at least one of the plurality of drive signals based on a time period from when the detecting signal is sent until the detecting signal is reflected and returned from the terminal of the one of the pair of signal lines.
