The present invention discloses a magnetic component and a manufacturing method thereof, wherein the magnetic component comprises a magnetic element and a peripheral structure. The magnetic element comprises a magnetic core and a winding, wherein the winding is embedded in the magnetic core, and a PIN foot is formed through the top surface and / or the bottom surface of the magnetic core. The peripheral structure is arranged adjacent to the peripheral side of the magnetic core. The magnetic element and the peripheral structure are combined to form a magnetic assembly, and one method for manufacturing the magnetic component is to thin the top surface and / or the bottom surface of the magnetic assembly through a thinning process, and another method is to thin the top surface and / or the bottom surface of the magnetic core through a thinning process, and / or, to thin the PIN foot of the magnetic core winding through a thinning process.
