WINDING TYPE COMMON MODE CHOKE COIL

PROBLEM TO BE SOLVED: To provide a winding type common mode choke coil which can be improved in degree of balance between a plurality of windings. SOLUTION: The winding type common mode choke coil 10 includes a magnetic core 11 having a core portion 11A and collar portions 11B at both ends thereof, first and second windings 12 and 13 wound around the core portion 11A vertically one over the other, and a plurality of electrodes (not shown) which are formed at the collar portions 11B and to which both end portions of the windings 12 and 13 are electrically connected, and the first and second windings 12 and 13 have conductor wires 12A and 13B, ferromagnetic coatings 12B and 13B covering the conductor wires 12A and 13A, and insulating resin coatings 12C and 13C covering the ferromagnetic coatings 12B and 13B.
