<p>PROBLEM TO BE SOLVED: To obtain an antenna for portable radio machine whose life or commodity value is prevented from being reduced. SOLUTION: A large-diameter part 30a is formed in the vicinity of the base end part of a conductive sleeve 13 in a joint part 30 to prevent the base end of the sleeve 13 from coming into contact with other parts by the large-diameter part 30 in pulling out and storing an antenna. Thus, problems are prevented which are caused by repeatedly bringing the base end of the sleeve 13 into contact with other parts to generate metallic powder.</p> |
