Abstract
Lightning receptor for a wind turbine rotor blade, the lightning receptor being produced in one part in a casting process and having a receptor tip, a receptor suction side, a receptor pressure side, a receptor nose edge and a receptor end edge, defined by a fastening portion with two mutually opposite adhesive bonding surfaces which are formed by recesses in the receptor pressure side and in the receptor suction side, a receptor-nose-edge-side leg and a receptor-end-edge-side leg projecting beyond the fastening portion in a direction away from the receptor tip.
