PURPOSE: An electromagnetic wave shield mouse is provided to minimize the harm influence due to the electromagnetic wave generated by the computer manipulation by shielding the electromagnetic wave against the mouse connecting to the computer main body through the wire or wireless mode. CONSTITUTION: A main body of the mouse has an electromagnetic wave shield layer fro shielding the electromagnetic wave radiating from inside of the mouse. The electromagnetic wave shield layer is formed inside of the mouse case, on the inner surface or on a semiconductor chip. The electromagnetic shield layer is connected to a ground part and is formed by the electromagnetic wave absorber such as Mn-Zn-, Ni-Zn- or Mn-Zn-ferrite of a grain size from 0.1 micrometer to 1 millimeter, or non-conductive materials such as mu-metal group nonferrous metal, magnesium alloy or silicon steel. |
