A relay device for data between communication cables having a signal line in full duplex communication, includes: communication units connected to the communication cables; and a main controller executing a relay process of the data. Each communication unit includes: an input/output unit of an analog signal; an analog/digital converter converting the analog signal into a digital signal; a generator generating another digital signal based on another analog signal input to another communication unit; and an echo canceller calculating a filter coefficient based on the other digital signal and the digital signal, and executing a cancellation process of removing a component derived from the other digital signal from the digital signal according to the filter coefficient. The communication unit or the main control unit includes a sign determination unit determining based on a time change of the filter coefficient whether a sign of disconnection exists in the signal line.
