Abstract: Provided is a wind power generation apparatus including a wind turbine blade that has a blade body and a receptor mounted on a tip of the blade body. The receptor includes a solid blade outer portion that is positioned on an outside of a tip opening portion of the blade body and a blade inner portion that is positioned on an inside of the tip opening portion. The blade inner portion includes a portion of which a size in a width direction or a thickness direction is greater than a size of an inner wall of the blade tip opening portion in the width direction or the thickness direction. An internal conductor connected to the receptor is provided on an inside of the blade tip opening portion. A fastening unit that fastens the blade inner portion and the blade body is provided. A portion of the blade inner portion of the receptor on which the fastening unit is mounted is formed in a block shape so as to cover the fastening unit in a length direction thereof.
