ことを特徴とする避雷手段の劣化表示装置。Of a pair of opposing electrodes that are inserted through protective covers at both ends of a transparent outer cylinder and supported by sealing plugs, one charging side electrode is fixed to the outer cylinder, and the other grounding side electrode is fixed to the outer cylinder. The inner end is formed into a cylindrical shape with a bottom and is movably inserted into the charging side electrode, one end is connected to the inner end of the charging side electrode, and the other end is connected to the grounding side electrode. a resistor that is separably connected to the inner peripheral surface of the cylindrical part, and a predetermined distance that covers the resistor and a part of the inner end of the charging side electrode, and between the inner end of the cylindrical part and the outer periphery of the charging side electrode. An insulating cylindrical spacer is provided so as to be spaced apart to form a discharge gap, and between the inner bottom of the cylindrical part of the ground side electrode and the resistor, the resistor is continuously maintained at a predetermined level. An incendiary agent is disposed that ignites due to heat generation of the resistor when a leakage current flows, and a vulnerable portion is provided in the ground side protective cover that ruptures due to a pressure increase generated at the inner bottom of the ground side electrode due to the ignition of the incendiary agent. A deterioration display device for a lightning protection means, characterized in that:
