摘要:
A wire wound electronic part includes a ferrite core comprising ferrite having a columnar wire wound core and flanges formed at both ends thereof, a coil conductor wound around the wire wound core of the ferrite core, and at least a pair of terminal electrodes having a Cu conduction layer disposed to the outer surface of the flange, in which both ends of the coil conductor wound around the wire wound core are conductively connected to the terminal electrodes. The terminal electrode is formed by coating an electrode paste containing a Cu powder and a glass frit to the outer surface of the ferrite core, and then applying a heat treatment to the ferrite core. There is a reaction layer of a portion of the ferrite core and the glass frit at a boundary between the ferrite core and the Cu conduction layer. The terminal electrodes has the peel strength identical with that of an existent Ag terminal electrode, without forming a plate layer.
