To effectively perform lightning protection in a blade for wind power generation and to prevent the blade from being damaged when arresting lightning. The lightning protection structure of the blade for wind power generation includes a conductive lightning receptor 1 attached to a part of the blade for wind power generation, and a ceramic member 10 interposed between at least surface-layer portions of the lightning receptor 1 and the blade 5. Therefore, an electric field is likely to concentrate at an interface between the ceramic member 10 having excellent heat resistance and the lightning receptor 1, so that it is possible to effectively prevent the blade 5 from being damaged due to a concentration of the electric field at the interface of the blade 5 attached with the lightning receptor 1 when arresting the lightning. |
