Claim 0:
1. A lightning suppression device for wind turbine blades that is provided at a tip of a wind turbine blade and suppresses lightning struck on the wind turbine blade, the device comprising:
an electrical insulator attached to the tip of the wind turbine blade and formed of a non-conductive material; an internal electrode attached to the electrical insulator on a side opposite to the wind turbine blade; and an external electrode attached to the electrical insulator so as to surround the internal electrode with a predetermined gap between the internal electrode and the external electrode, wherein
the electrical insulator is fixed to the tip of the wind turbine blade by a fixing member,
a ground line is connected to the internal electrode,
the internal electrode and the external electrode form a capacitor, and
the internal electrode is formed into a plate shape.
