To provide a laminated sheet, which, while guiding a destination of electric discharge of static electricity certainly, the influence of the electromagnetic field produced by the electric discharge can be eliminated, and to provide the printed wiring board equipment and the electronic parts equipped with it.
By constituting the laminated sheet 7 for protecting the printed wiring board 6 from the static electricity discharge with a laminate of a electricity conductive sheet material 8 and an electricity non-conductive magnetic sheet material 9, while guiding the electric discharge of static electricity to the upper conductive sheet material 8 certainly, the electromagnetic field produced by the electric discharge is absorbed by both the sheet materials 8 and 9.
