<p>PROBLEM TO BE SOLVED: To provide a laminated common-mode choke coil whose layer coupling coefficient between conductor layers can be improved. SOLUTION: In this laminated common-mode choke coil 1, a first conductor layer W1 for winding and a second conductor layer W2 for winding which are in a spiral shape and provided independently of each other are counterposed to each other in a state in which they are overlapped at least in two stages in the direction vertical to a spiral plane. Also, both conductor layers W1, W2 are sandwiched by plate-like magnetic bodies F, F. In this case, one of the conductor layers W1, W2 and the other are disposed so as to be alternately next to each other, in both the horizontal and vertical directions in the spiral plane.</p> |
