The present invention relates to an electrical leak detecting apparatus for an electric vehicle, which is capable of not only detecting an electrical leak generated when a vehicle body is connected to the maximum potential or minimum potential of a battery pack, but also detecting which portion of the battery pack the vehicle body is connected to when an electrical leak is generated through the connection of the vehicle body and an intermediate potential of the battery pack. The electrical leak detecting apparatus for an electric vehicle according to the present invention includes: first and second switches connected to each other in series between a maximum potential terminal and a minimum potential terminal; a detection resistor having one end connected to a common contact of the first and second switches; and first and second measured potential supply units which are connected to each other in parallel between the other end of the detection resistor and the vehicle body, and which selectively provide first and second measured potentials, of different potential, to the battery pack.
