PROBLEM TO BE SOLVED: To provide a wire-wound coil capable of suppressing variation in the L value, even of a product where the number of turns of a coil part is small.SOLUTION: A wire-wound coil includes a core 2 having flanges 2b, 2c at the opposite ends of a square columnar core 2a in the longitudinal direction, electrodes 3 provided in respective flange 2b, 2c, and a conductor 4 wound in a coil shape around the core 2a while being bonded to these electrodes 3. The conductor 4 has a pair of lead lines 4a, 4b led out from the electrode 3 to the core 2a, in non-contact. The part excepting both lead lines 4a, 4b is a coil part 4c, which is wound only 3,4 turns roughly so that the adjoining conductors 4 are separated from each other, and the end of the first turn of the coil part 4c is abutting against the end of the lead line 4a on the start-of-winding side at point P.SELECTED DRAWING: Figure 2 |
