PROBLEM TO BE SOLVED: To miniaturize an electromagnetic-wave shield housing without damaging its electromagnetic-wave shield effect, in the electromagnetic-wave shield housing so constituted as to be able to store electronic components therein and suppress the inputting/outputting of the electromagnetic wave to/from the electronic components. SOLUTION: Fig. 3 shows such a state that in an electromagnetic-wave shield housing of an embodiment a printed wiring board 90 is so fastened onto a spacer 18 by a screw 91 as to be covered with a cap portion 20. A rubber sheet 22 filled with a ferrite is stuck on the surface of the inner wall of the cap portion 20, and since a hole portion 24 is drilled in the opposite portion to the spacer 18 with respect to the rubber sheet 22, the head portion of the screw 91 is engaged with the hole portion 24. Since the head portion of the screw 91 is made of a metal, all the electromagnetic waves intended to pass through the hole portion 24 are reflected by the head portion of the screw 91, and the rubber sheet 22 absorbs the electromagnetic wave. Also, since the head portion of the screw 91 is engaged with the hole portion 24, even though the rubber sheet 22 is not thinned extremely, any unavailable space present in the inside of the electromagnetic-wave shield housing can be reduced effectively.
