Abstract
A portable telephone device can inform the surroundings unintentionally that a user is talking during speaking on the portable telephone. A speaking state display means that goes on and off during speaking is provided on a back surface side of a body case in relation to an operational surface side thereof and at a position where it is not covered with a hand when a user holds a portable telephone device. When it is detected that the portable telephone device enters on the speaking state, the speaking state display means is turned on and off by a control means at regular intervals while the brightness is being gently increased or gently decreased, whereby the speaking state display means is turned on and off just like a firefly. Further, the brightness is set to a low degree by which a person near the portable telephone device can identify the brightness, whereby the consuming electric power of a battery is suppressed low and a hindrance to the speaking time of the portable telephone is prevented.
