PURPOSE: A leak sensing apparatus is provided to confirm accurate leak occurrence position sensed by a reverse direction and a right direction and minimize a sensing line. CONSTITUTION: A conductive line(410) has a conductivity to a lengthy direction. A first resistance line(420) is formed parallel with the conductive line to the lengthy direction. A second resistance line(430) is formed parallel with the first resistance line to the lengthy direction. The second resistance line is electrically connected with the first resistance line on a position. A controller alternatively supplies a power source to the first resistance line and the second resistance line. The controller produces a distance with gaining a resistance value from the conductive line in a leak generation.
