A leading-edge protector element for protecting a leading-edge of a wind turbine blade is provided. The leading-edge protector element includes a film layer and a rubber layer, and is provided on a coiled-up roll. The leading-edge protector element has a thickness between a first edge, a second edge, a third edge, and a fourth edge. The thickness decreases along a transverse direction towards the third edge and towards the fourth edge. The leading-edge protector element for protecting a leading-edge of a wind turbine blade may alternatively only include a rubber layer and also be provided on a coiled-up roll.
