Zusammenfassung:PROBLEM TO BE SOLVED: To provide a cellular telephone provided with an antenna which does not protrude toward the outside of a casing and can obtain full sensitivity within a small space. SOLUTION: A conductive layer is formed on the outer surface of a housing case 4 for housing an electronic circuit 3 in the casing 1 forming the cellular telephone, and this conductive layer is used as the antenna 5. With this configuration, an antenna function can be obtained without securing a special space for housing the antenna, and the configuration can easily achieve the miniaturization of the cellular telephone.
