To provide a wire-winded type electronic component having a peel strength equivalent to that of the existing Ag electrode without forming a plating layer.
The wire-winded type electronic component 10 comprises: a ferrite core 11 composed of the ferrite and having a columnar core part 11a and stops 11b, 11c formed on its both ends; a coil conductor wire 12 winded around the core part of the ferrite core; and at least a pair of terminal electrodes 16A, 16B comprising a Cu conductive layer 16a provided on the outer surface of the stop with the both end part of the coil conductor wire winded around the core part conductively connected to the terminal electrode. The terminal electrode is formed by coating an electrode paste including a Cu powder and a glass frit to the outer surface of the ferrite core, and then, by heat-treating the ferrite core. The interface between the ferrite core and the Cu conductive layer has an reactive layer of a part of the ferrite core and the glass frit. This provides the peeling strength equivalent to that of the existing Ag electrode.
