<p>The present invention relates to an alkali solution leak detection apparatus. The purpose of the present invention is to provide an apparatus for alkali solution leak detection that is capable of selectively detecting only alkali solution by preventing a coating layer from being melted in water by coating the coating layer on a conductive line. To this end, the device according to the present invention comprises: a base film layer made up of a film material; a pair of conductive lines formed lengthwise in parallel with each other on the upper surface of the base film layer; and a coating layer applied to the upper surface of the base film layer so as to cover the conductive lines preventing the conductive lines from being exposed to the exterior by substance that has changing resistance responding to an alkali solution. The coating layer is formed by 60-80 wt% of resin that can be dissolved or infringed by an alkali solution, 1-40 wt% of volatile solvents and 1-10 wt% of a hardening agent.</p> |
