Summary:The utility model provides an electronic device. The electronic device comprises a substrate; the first shielding layer is arranged above the substrate; the second shielding layer is arranged below the substrate, and the thickness of the second shielding layer is larger than that of the first shielding layer. In order to solve the technical problems that the thickness of a shielding layer formed by a conventional sputtering coating process is limited and the requirement is difficult to meet under the condition that a relatively thick shielding layer is needed due to a low-frequency shielding requirement, the utility model provides the electronic device. The shielding layers with different thicknesses are respectively arranged above and below the substrate, the shielding requirements of low frequency and high frequency (relative to the low frequency) can be met, the shielding requirement of the low frequency generally appears on the bottom surface of a DSM (Double-side molding) structure, the shielding layer w
