Abstract
The present disclosure provides a magnetic element and a method for manufacturing same. The method includes: forming a first metal wiring layer on a surface of at least one segment of a magnetic core; forming a first metal protection layer on the first metal wiring layer; removing a portion of the first metal protection layer with a direct writing technique to expose a portion of the first metal wiring layer; and etching the exposed first metal wiring layer in such a manner that the first metal wiring layer forms at least one first pattern to function as a winding, where at least one turn of the first pattern surrounds the magnetic core. The magnetic element and the method for manufacturing the magnetic element provided in the present disclosure can improve space utilization of the magnetic element.
