Patent ID: 7782049

Claim:
A magnetic device comprising: a first substrate having a first conductive layer and a second conductive layer; a second substrate having a third conductive layer and a fourth conductive layer; a magnetic element that is placed between the first substrate and the second substrate; a first connecting portion that electrically connects the first conductive layer and the third conductive layer; a second connecting portion that electrically connects the second conductive layer and the fourth conductive layer; a coil-shaped first magnetic field generating device that includes the first conductive layer, the third conductive layer, and the first connecting portion; a coil-shaped second magnetic field generating device that includes the second conductive layer, the fourth conductive layer, and the second connecting portion; a first magnetic field induction device that passes through the center of the coil shape of the first magnetic field generating device; a second magnetic field induction device that passes through the center of the coil shape of the second magnetic field generating device; and a third substrate that is placed between the first substrate and the second substrate, and the third substrate has a magnetic element housing portion, which houses the magnetic element, a first housing portion, which houses the first magnetic field induction device, and a second housing portion, which houses the second magnetic field induction device, and wherein the magnetic element housing portion is placed between the first housing portion and the second housing portion.
