Abstract: Disclosed herein is a polyvinyl chloride (PVC) hose with a leak notification function. The PVC hose includes: an inner layer configured such that a fluid is transferred through a hollow; a reinforcing yarn layer wound around the inner layer, and configured to increase the pressure of the inner layer and restrain expansion; an intermediate layer formed through coating around the reinforcing yarn layer; a first electrode layer formed through coating around the intermediate layer, and provided with a first terminal; a partition layer formed through coating around the first electrode layer; a second electrode layer formed through coating around the partition layer, and provided with a second terminal; a high-density woven yarn layer processed around the second electrode layer; an outer coating layer formed through coating around the high-density woven yarn layer; and a leak detection device configured to determine whether there is a leak depending on whether current is conducted.
