The lightning protection device of a windmill blade in which a receptor, to be attached to the tip end of a blade where a blade profile is particularly reduced in size, is simple in structure and easy to assemble, a receptor for lighting strike is installed on the surface of a blade in order to take an effective action against a pressure rise occurring within a blade when lighting strides the blade, and lighting current from the receptor is earthed to the ground via a conductor wire passed through the inside of the blade and the windmill body or via a connection apparatus such as a bypass brush, characterized in that a base plate consisting of a conductor and having the conductor wire connected thereto is buried in the blade, and a receptor assembly formed by fixing the receptor to the base plate to be supported thereon and to face the surface of the blade is provided; and a method of assembling the lightning protection device. |
