PROBLEM TO BE SOLVED: To provide a portable terminal device capable of increasing the design and the visibility by preventing the light from a light-emitting part from leaking to the outside with a dark color part which absorbing the light, which is formed between the light-emitting part and a light-translucent part.SOLUTION: A pusher sheet 203 is laminated over the rear side of the key top sheet 201. A flexible substrate 102 is formed opposing to the rear side of the pusher sheet 203. The light-emitting part 122a is disposed on a plane opposing to the pusher sheet 203 of the flexible substrate 102 to illuminate the back side of a key top 111a via the pusher sheet 203. The light-translucent part R1 allows the light from the light-emitting part 122a to transmit therethrough. The dark color part 301 is formed between the light-emitting part 122a and the light-translucent part R1 on the rear side of the pusher sheet 203 to absorb the light from the light-emitting part 122a. |
