Abstract: PURPOSE: To provide a mobile communications terminal with a key button illumination device that improves the illumination efficiency by causing the light emitted from a light-emitting device to be reflected by the wall of the shield case. CONSTITUTION: A key button structure comprises a case 18, a shield case 10 surface-treated with a metal, key button, and printed circuit board 8 with a light-emitting device. The light-emitting device 22 such as LED is enclosed by ribs 21 erected in the shield case 10. This overcomes the space problem together with improving the illumination efficiency.
