PROBLEM TO BE SOLVED: To solve the problem that the electromagnetic-shielding performance of the abutting sections of the mutual end sections 1a and 1a of each gypsum board 1 and 1 is deteriorated because the mutual conductive materials of each gypsum board 1 and 1 are not connected electrically in the abutting sections and electromagnetic waves are easy to lead through a whit gap formed in the abutting sections. SOLUTION: In an electromagnetic-shielding structure in which a plurality of tabular building materials containing the conductive material are installed by mutually abutting the end sections of the tabular building materials gypsum boards 1 against core materials gypsum-board constituting sections 2, conductive plates such as conductive long-sized plates 10 are mounted on the exposed sections abutting sections 8A of the core materials of each tabular building material, and each tabular building material is connected electrically through the conductive plates.
