Abstract

Antenna characteristics of a folding cellphone are adjusted to appropriate values. The cellphone includes a first casingcontaining a first circuit member, and a second casingcontaining a second circuit member. The first circuit memberand the second circuit memberare connected by a connection structure consisting of a first connecting conductorextending from each lateral end of the first circuit memberdownward (toward the second casing), and a second connecting conductorextending from each lateral end of the second circuit memberupward (toward the first casing). The first circuit memberand the second circuit memberare each comprised of shields, substrates, and so on. Antennais disposed at an upper edge of the first casing. The effective casing length is affected by the length of the first casingand the second casing, which are both electrically conductive. The end of the first connecting conductoris formed by a first circular portionhaving a circular opening. The second connecting conductorhas a second circular portionand an openingat the tip thereof, which are shaped similarly to those of the first connecting conductor. A spacermade of an insulator is inserted between the first and second connecting conductors.
