To reduce adverse influence to a human body by means of an electromagnetic wave, to give ease feeling to a user, to improve the radiation characteristic of the electromagnetic wave and to facilitate the pull-out/pull-in of an antenna even in a calling posture by fitting the antenna fitting position of a handy communication unit to the lower part of a main body.

An antenna fitting position while a handy communication unit is used is set to the lower part 3 of a main body and it is kept away from brain and a heart as far as possible. Since the antenna position during use is set to the lower part 23 of the main body, adverse influence to the human body owing to an electromagnetic wave is reduced and ease feeling can be given to a user. The radiation characteristic of the electromagnetic wave improves, the pull-out/pull-in of the antenna become easy and production cost can be made almost similar to a former case. Even if the most part of the antenna is pushed into the main body 1, or it is pulled out halfway, the maximum point of electromagnetic wave voltage is prevented from being closely stuck to a brain cell which is most anxious in the human body and the effect in health and mind is given.
