Antenna characteristics of a folding cellphone are adjusted to appropriate values. The cellphone includes a first casing 10 a containing a first circuit member 15 a, and a second casing 10 b containing a second circuit member 15 b. The first circuit member 15 a and the second circuit member 15 b are connected by a connection structure consisting of a first connecting conductor 23 a extending from each lateral end of the first circuit member 15 a downward (toward the second casing), and a second connecting conductor 25 a extending from each lateral end of the second circuit member 15 b upward (toward the first casing). The first circuit member 15 a and the second circuit member 15 b are each comprised of shields, substrates, and so on. Antenna 111 is disposed at an upper edge of the first casing 10 a. The effective casing length is affected by the length of the first casing 10 a and the second casing 10 b, which are both electrically conductive. The end of the first connecting conductor 23 a is formed by a first circular portion 31 a having a circular opening 31 c. The second connecting conductor 25 a has a second circular portion 31 b and an opening 31 d at the tip thereof, which are shaped similarly to those of the first connecting conductor 23 a. A spacer 27 a made of an insulator is inserted between the first and second connecting conductors.
