Provided is a wind turbine blade for a wind turbine, the wind turbine blade including an electrical conductor extending in a longitudinal direction of the wind turbine blade, and a carbon fiber material being electrically conductive and having a first portion which is arranged beside the electrical conductor, a second portion which is connected to the first portion and is attached and electrically connected to the electrical conductor, and a third portion which is connected to the second portion and at least partially overlaps with the first portion. Due to such an electrical connection between the electrical conductor and the carbon fiber material arcing and, thus, delamination of carbon can be avoided when conducting current of a lightning strike.
