Abstract
A leak sensor apparatus for sensing moisture is disclosed, which is prepared in such a manner that a base film layer, a conductive line layer and a protection film layer are sequentially stacked on its lower surface in an upward direction, and said conductive line layer includes a resistance line having a certain resistance value per unit area in a longitudinal direction, and a conductive line which is spaced apart from the resistance line and is formed in parallel with respect to the resistance line, and said protection film layer is provided with a plurality of holes which are formed at regular intervals so that the resistance line and the conductive line of the conductive line layer can be exposed to the outside through the holes, respectively.
