MAGNETIC COMPONENT AND ELECTRIC POWER TRANSMITTER

摘要

PROBLEM TO BE SOLVED: To provide a magnetic component capable of preventing diffusion of magnetic flux out of the magnetic component.SOLUTION: The magnetic component includes: first wiring; and second wiring which is isolated from the first wiring, and which makes magnetic coupling with the first wiring. The first wiring is wound to form a first coil, and the second wiring is wound on the same axis as the first wiring to form a second coil. The second wiring forming the second coil is disposed in an area X and an area Z. The first coil and the second coil are disposed at a position where the following formula 1 and formula 3 are satisfied: r1min>rX (formula 1); r1max
