Abstract
Provided is a leakage detector which is capable of exhibiting high sensitivity to vibration-sounds caused by water leakage from a synthetic resin pipe and thus setting an installation span longer to thereby make it possible to more efficiently perform a water leakage inspection for a synthetic resin pipe. The leakage detector () comprises a base (), a piezoelectric element () supported by the base () and configured to convert vibration-sounds to an electric signal, and a weight member () loaded against the piezoelectric element (). The piezoelectric element () is made of a polymeric piezoelectric material. One end of the piezoelectric element () is supported by an upper end of a support post (), and the weight member () is loaded against the other end of the piezoelectric element ().
