Abstract

There is provided a mobile terminal apparatus in which downsizing of the mobile terminal apparatus can be achieved and an antenna characteristic can be suitably supplied.

In a mobile terminal apparatus 10, upper and lower housing 13 and 15 are coupled with each other by a coupling part 18 so as to be openable and closable, upper and lower circuit boards 21 and 24 are provided in the upper and lower housing 13 and 15, upper and lower protective cover parts 31 and 32 cover the upper and lower housing; and a flexible part 33 couples the upper and lower protective cover parts so as to be openable and closable and covers the coupling part. In the mobile terminal apparatus 10, an antenna power feeding land 51 is provided in one of the upper and lower circuit boards, a power feeding terminal of the antenna part 40 is electrically connected to this one circuit board via the antenna power feeding land, and the antenna part is housed in the flexible part.

Claims
