Abstract
Abstract A compact portable telephone, in which a sufficient distance between the receiving portion and the voice inlet portion can be secured when the telephone is used. A flexible pipe member formed of metallic or dielectric material is slidably or swingably attached to the main body of the telephone or has its base fixedly attached to the main body. The flexible pipe member is provided at its end with a microphone. When the flexible pipe member is formed of metallic material, the flexible pipe member is used as an antenna. When the flexible pipe member is formed of dielectric material, at least one of a pair of cords connected to the microphone is utilized as an antenna.
