Claims

[Scope of utility model registration request]

An electrolytic corrosion apparatus in which a corrosive liquid penetrating substance is brought into contact with the planned corrosion location of the specimen, a cathode lead wire is connected to the corrosive liquid penetrating substance, and an anode lead wire is connected to the specimen near the corrosive liquid penetrating substance. an insertion tube whose one end is closed with an end plate and a side opening cut out on a side surface near the one end; a cathode plate arranged in the center of the side opening and connected to the cathode lead wire; The corrosive liquid penetrating substance is filled in the tube and supports the cathode plate, and the part protruding from the side port can come into contact with the inner surface of the specimen, and the material is fixed to the outer surface of the insertion tube so that its tip can come into contact with the specimen. A narrow area electrolytic corrosion apparatus characterized by comprising: an anode plate;
