Abstract
The present invention relates to an oil leak detection device. In an aspect, the oil leak detection device includes a base film layer 200 configured in a tape form, a pair of polymer lines 220, 230 formed on a top surface of the base film layer in parallel in a length direction, a pair of conductive lines 210, 240 formed on the top surface of the base film layer in parallel to the pair of polymer lines in the length direction, and an upper protection film layer 300 attached to the top surface of the base film layer and configured to have a plurality of sensing holes 310 formed at specific intervals in the length direction at locations through which only one of the pair of polymer lines is exposed.
