<p>PURPOSE:To improve productivity and workability while decreasing defective products by providing a conductor pattern to define a coil on either principal face of a ferrite layer, the conductor patterns being connected electrically via a through hole to complete a coil, and providing external electrodes on the outer ends of the ferrite layer and outer ferrite layers, the external electrodes being electrically connected with the ends of the conductor patterns. CONSTITUTION:A first conductor pattern 26 is provided on one principal face of a ferrite layer 22 such that 0.75 turn of the conductor pattern extends from one end of the principal face to a through hole 24 along the peripheral edge of the ferrite layer 22. On the other principal face of the ferrite layer 22, there is provided a second conductor pattern 28 such that 0.75 turn of the conductor pattern extends from the other end to the through hole 24 along the peripheral edge of the ferrite layer 22. The first conductor pattern 26 is electrically connected with the second conductor pattern 28 via the through hole 24, whereby 1.5 turns of coil is defined. A pair of external electrodes 32 are provided on the outer ends of the ferrite layer 22 and outer ferrite layers 30 and are electrically connected with the end 26a of the first conductor pattern 26 and the end 28a of the second conductor pattern 28.</p> |
