To provide a rail breakage detection device capable of detecting a breakage of a rail with a simple device configuration before a train comes, and also partitioning the detection section smaller as necessary.SOLUTION: In order to detect a breakage of a rail, a plurality of bonds that connect right and left rails are prepared, the currents are fed to the right and left rails via a central power transmission bond, the currents fed to the right and left rails are merged at a terminal power reception bond, and then is returned to a power supply using a return current line. A breakage diagnosis box is mounted to the power reception bond to always diagnose whether or not the currents flowing in from the right and left rails are balanced. If it can be confirmed that the currents are balanced, it is determined that there is no breakage of the rail, and if the currents are not balanced, it is determined that there is a breakage of the rail. Furthermore, in order to increase the diagnostic resolution of rail breakage, a breakage of the rail adjacent to the diagnostic bond is detected by connecting the diagnostic bond to the rail at any location between the power transmission bond and the power reception bond, and measuring the presence or absence of current flowing through the diagnostic bond.SELECTED DRAWING: Figure 2
