Abstract

PURPOSE:To provide a waterproof magnetic member which prevent the corrosion even if it is used under water and dows not impair the breeding of life by covering a waterproof layer on the member. CONSTITUTION:The magnetic member becoming a permanent magnet 9 of various shape is covered with the waterproof layer 10 formed of heat-shrinkable plastic or the like. The entire periphery of a structure associated with cylindrical permanent magnets 13, 14 is covered similarly with the heat-shrinkable plastic to thus form the waterproof layer 10. THe layer can also be formed by covering epoxy resin thereon at this time. The waterproof layer thus formed can prevent the corrosion due to marine water and fresh water and lack of oxygen in water so as not to impair the breeding of the life.
