A structural body of the present invention comprises a first member ( 1 ) having a first outside end portion ( 10 ) in which a first metal element is adapted to a major component; a second member ( 2 ) having a second outside end portion ( 20 ) in which a second metal element, being different from the first metal element, is adapted to a major component, and which is disposed to contact with the first outside end portion ( 10 ); and a coating member ( 3 ) comprising a coated film, at least whose outside superficial portion is composed of a fluoropolymer substance, and coating at least a part of both first outside end portion ( 10 ) and second outside end portion ( 20 ) so as to cover the contact portion ( 50 ) between them. Moreover, an electric-corrosion prevention method of the present invention, in the aforementioned structural body, inhibits the development of electric corrosion, which might possibly occur so as to stride over the contact portion ( 50 ) between the first outside end portion ( 10 ) and the second outside end portion ( 20 ), by hindering the electric conduction between the first outside end portion ( 10 ) and the second outside end portion ( 20 ) by means of the coating member ( 3 ). In accordance with the structural body and electric-corrosion prevention method of the present invention, the electric corrosion between members of different metals can be prevented effectively. |
