To provide a fiber sheet body which is much more suitable as a lead wire to be used for a fiber sheet, and which is more excellent in the contact property of a lead wire.

A fiber sheet body 1 is provided with: a fiber sheet 10 having two conductive fibers 11 and two lead wires 20 configured of highly intense fiber worked by plating. Also, two lead wires 20 are respectively sewed in the fiber sheet 10 so as to be brought into contact with the two conductive fibers 11. Also, the fiber sheet 10 is configured of warp and weft such as polyester, and two of the warp and weft are configured as the conductive fibers 11. Also, aramid fiber, polyarylate fiber and PBO fiber or the like are used as highly intense fiber.
