Mobile terminal device

Abstract

In a mobile terminal device, a hinge member and a conductive member provided on a chassis and functioning as an antenna are electrically contacted with each other through the slide operation of a chassis and thereby can be configured as an antenna usable in various use situations without providing a separate antenna. Consequently, the mobile terminal device is provided, the manufacture cost of which can be suppressed, the size and thickness of which can be reduced, and which can prevent antenna characteristics from degrading because the antenna is not provided at a portion gripped by a hand. In the device, a first chassis (101) has a radio circuit (112). A second chassis (102) has a ground plate (121) and is attached so as to be freely slidable with respect to the first chassis (101). A tilt hinge member (104a) rotatably connects the first chassis (101) to the second chassis (102), is fed from the radio circuit (112), and functions as an antenna together with the ground plate (121) when the hinge member is electrically contacted with the ground plate (121) through the slide operation of the second chassis (102).
