To provide an outflow-current detecting apparatus, whereby the attaching work of a lead wire to it is made simple, and its repeated use accompanied by no replacing component is made possible, and the view of the reporting relative to an outflow current is much facilitated, and further, drive power-supply for it is not required.

The current-detecting apparatus for sensing and reporting the current-outflow, generated from a class of electrical appliance associated with power feeding equipments has a lead-wire fetching means for fetching in the apparatus the lead wire connected with the class of electrical appliance and extended therefrom; a sensor means for detecting the outflow current flowing through the lead wire; a conversion means for converting the sensed outflow current into a voltage signal; and a reporting means for reporting to users the information of the outflow current, based on the data obtained by these means.
