The invention provides an electromagnetic interference shielding structure, which belongs to the technical field of electromagnetic interference screens and can solve the problem of poor shielding effect of an existing electromagnetic interference screen. In the electromagnetic interference shielding structure, a second metal layer subjected to patterning and a first metal layer are connected through the through hole of an insulation layer between the second metal layer and the first metal layer. When the electromagnetic interference shielding structure is used, the first metal layer approaches to a component to be protected, the second metal layer subjected to patterning is far away from the component to be protected, so that the second metal layer subjected to patterning shields the electromagnetism of other radiation sources, and can reflect the electromagnetism back; and the whole first metal layer shields own electromagnetism to avoid disturbing other components. The electromagnetic interference shielding structure has a good shielding effect, is suitable for the electromagnetic protection of each field and is especially suitable for electromagnetic protection among a high-frequency signal line, the pins of an integrated circuit, various classes of plugins and the like in a printed circuit board.
