An electrostatic discharge protection (ESD) structure for protecting a core circuit of an integrated circuit from an ESD event received by a conductive pad of the integrated circuit is provided. The ESD protection structure includes a first conductive layer, a clamp device, a first electrical connection part and a second electrical connection part. The first conductive layer is formed below the conductive pad, and includes a first conductive portion, an insulating portion and a second conductive portion. The insulating portion is surrounded by the first conductive portion and the second conductive portion. The first conductive portion is electrically connected between the conductive pad and the second conductive portion. The clamp device is arranged for clamping the ESD event. The first electrical connection part is coupled between the first conductive portion and the clamp device. The second electrical connection part is coupled between the second conductive portion and the core circuit.
