An electronic module includes a circuit board, a plurality of electronic components, a plurality of molding layers, at least one first conductive layer, at least one insulating filler, and one second conductive layer. The circuit board has a first plane and at least one grounding pad on the first plane. The electronic components are mounted on the first plane and electrically connected with the circuit board. The molding layers cover the electronic components and the first plane. The trench appears between two adjacent molding layers. The grounding pad is positioned at the bottom of the trench. The first conductive layer covers the sidewall of the trench and the grounding pad. The grounding pad electrically connected with the first conductive layer. The insulating filler is positioned in the trench. The second conductive layer covers the molding layers and the insulating filler, and electrically connects with the first conductive layer.
