Abstract
A portable radio device of a type having two-direction openable and closable enclosures that can effectively lessen influence on an antenna exerted by a hinge section is provided. A horizontal hinge sectionfor rotatably joining an upper enclosureto a hinge enclosurearound a first shaft center includes a horizontal hinge anchorelectrically connected to a first metal partdisposed in the upper enclosure, a horizontal hinge platethat is placed in the hinge enclosureand that contains a conductive material, and a first hinge shaftthat electrically connects the horizontal hinge anchorto the horizontal hinge plateand that contains a conductive material interposed between an area from a substantial center to an end of a long side of a face along which the upper enclosureand the hinge enclosureface a direction of second shaft center (X). An electrical path length of the lateral hinge sectionincluding the lateral hinge plateand the first hinge shaftcorresponds to a predetermined value that is not a substantially constant multiple of λ/8.
