PROBLEM TO BE SOLVED: To make a configuration simple and to promote to make an antenna broadband and also high gain. SOLUTION: A flexible substrate 118, where an antenna element 119 and a matching circuit 120 are formed, is wound in an antenna cap 110 to be attached to a terminal body 10, a rod-shaped antenna 122 provided extendably inside the flexible substrate 118 is installed in a freely housable way, and antenna element 123 of the rod-shaped antenna 122 is subjected to capacitive coupling or disconnection with/from the matching circuit 120 of the flexible substrate 118 linked with the extension or housing of the rod-shaped antenna 112 and works in cooperation with the antenna element 119 of the flexible substrate 118 so as to control the structure of an antenna trimmer.
