<P>PROBLEM TO BE SOLVED: To provide an insulating member and a radio wave receiving apparatus, which prevent surely electric conduction through a metal fixing screw, and also prevent generation of a flaw caused by fastening of the fixing screw. <P>SOLUTION: The radio wave receiving apparatus is equipped with: a metal case body 3 storing an antenna device 9 inside; a metal back lid 6 mounted on the back surface of the case body 3; a plurality of metal fixing screws 7 for fixing the back lid 6 and the case body 3; and a plurality of insulating members 20 interposed between the plurality of fixing screws 7 and the back lid 6. When the metal case body 3 and the metal back lid 6 are fixed by the plurality of metal fixing screws 7, an electrically conduction situation of both components is prevented by electric insulation action of the plurality of insulating members 20, and reflux of a magnetic flux generated from the antenna device 9 into the metal case body 3 and the back lid 6 through the metal fixing screws 7 is suppressed, to thereby suppress surely decline of reception sensitivity of the antenna device 9. <P>COPYRIGHT: (C)2011,JPO&INPIT |
