Inductor device and method of manufacturing the same

An inductor device comprising:

• an insulating layer;
• a coil pattern disposed on two opposing surfaces of the insulating layer;
• a first insulating film and a second insulating film formed with different insulating materials, the first insulating film surrounding a curved exterior of the coil pattern, the second insulating film is sequentially disposed over the first insulating film on the insulating layer between adjacent turns of the coil pattern;
• and
• a magnetic member disposed to enclose the insulating layer, the coil pattern, and the first and the second insulating films,
• wherein the first insulating film comprises a first insulating material having a greater adhesive strength than the second insulating film, and the second insulating film comprises a second insulating material having a greater breaking strength than the first insulating film.
