A reception line break detection apparatus includes a transmission-side line drive, a reception line, a switching element, and a reception-side line receiver receiving signals transmitted from the transmission-side line drive through the reception line. The apparatus further includes a break detection unit detecting a break of the reception line using the switching element, where the switching element is switched according to a line voltage of lead-in wires branched off from the reception line. Accordingly, the apparatus includes fewer components than conventional apparatuses and fewer power sources are required.
