<p>Coil conductor pattern layer (2, 3, 4) are stacked to serve as U-shaped coil conductors (2A, 3A, 4A). The coil conductors (2A, 3A, 4A) are electrically connected in series through a via hole (15) for interlayer connection made in ceramic green sheets (10, 11) and form a spiral coil (L). Lead-out conductor pattern layers (5, 6) are also stacked to serve as lead-out conductors (5A, 6A). The lead-out conductor pattern layers (5) are arranged, one for each of a predetermined number of coil conductor pattern layers (2). One edge (51) of each lead-out conductor pattern layer (5) is in contact with the coil conductor pattern layers (2). That is, the thicknesses of the lead-out conductors (5A, 6A) are less than those of the coil conductors (2A to 4A).</p> |
