An electronic assembly according to an embodiment includes: a circuit board including a first edge surface and a trace having an electrical conductivity; an electronic element including a lateral edge spatially spaced apart from the first edge surface, and mounted on the circuit board and electrically connected to the trace; a protection layer including a second edge surface and disposed on the electronic element to substantially cover the electronic element; a magnetic field shielding film including a third edge surface and disposed on the protection layer; and a first metal layer. The first edge surface connects a main top surface of the circuit board and a main bottom surface of the circuit board, the second edge surface connects a main top surface of the protection layer and a main bottom surface of the protection layer, and the third edge surface connects a main top surface of the magnetic field shielding film and a main bottom surface of the magnetic field shielding film, and the first edge surface, the second edge surface, and the third edge surface are substantially aligned with one another to form a coupling edge surface which is substantially planar. In addition, the first metal layer is disposed on the magnetic field shielding film, and covers the main top surface of the magnetic field shielding film and the coupling edge surface.
