A high frequency electromagnetic induction element (1) comprises a magnetic core and a winding and also comprises a built in base (2). A base plate (21) of the built in base (2) is arranged inside the high frequency electromagnetic induction element (1) and is bound to the magnetic core by means of the winding. Multiple supporting legs (22) of the built in base (2) are connected onto the base plate (21) and extend out of the high frequency electromagnetic induction element (1) to be supported on a supporting carrier. Because the base plate (21) of the built in base (2) is arranged inside the high frequency electromagnetic induction element (1) and is bound to the magnetic core by means of the winding the built in base (2) and the magnetic core can be firmly fixed together to form into a whole and accordingly the looseness or even failure of the connection between the built in base (2) and the magnetic core cannot occur even when the high frequency electromagnetic induction element (1) produces high frequency vibration. Meanwhile the high frequency electromagnetic induction element (1) employs the built in base that has a simple structure for fixing and therefore the heat dissipation performance is good and the cost is low.
