The invention discloses an electrostatic shield applied to an image sensor chip. The electrostatic shield comprises a shielding part, and is characterized in that: the electrostatic shield is made from a flexible printed circuit (FPC) material; the center of the shielding part is provided with an accommodation hole for accommodating the image sensor chip; the shape of the accommodation hole is consistent with that of the image sensor chip; the periphery of the accommodation hole is provided with a protective wall which extends upwards from a shielding part body; a positioning part formed from the shielding part body to the horizontal direction is arranged on the edge of the shielding part, and is provided with round grounding positioning holes. The invention has the advantages that: the electrostatic shield made from the FPC material can effectively reduce external electromagnetic radiation interference, and is easy to machine and mold into a shape which is matched with that of the image sensor chip required
