PROBLEM TO BE SOLVED: To provide an attaching structure of a substrate for attaching the substrate of a mobile phone to its metal chassis, with which the substrate can be simply attached to the chassis while both the substrate and the chassis are surely grounded and thereby malfunction and noise of the mobile phone can be prevented. SOLUTION: Nut insertion holes 12 are formed on the chassis 11. A metal nut 13 for substrate attaching which has a throttling aperture 13b formed in its center 13a, a screw-tap formed on the inside of the throttling aperture 13b and a fitting portion 13c projectingly formed in a peripheral portion of the throttling aperture 13b, is inserted in the nut insertion hole 12. Screw insertion holes 10a are formed through the substrate 10, at positions corresponding the nut insertion holes 12. The substrate 10 is fastened on the chassis 11 by inserting the screws 14 through the screw insertion holes 10a and fastening the screws to the throttling apertures 13b. COPYRIGHT: (C)2008,JPO&INPIT
