<P>PROBLEM TO BE SOLVED: To provide an antenna for a portable terminal, which can enhance durability by increasing strength against a bending load of a part made of a thin-walled tubular antenna element. <P>SOLUTION: An antenna 1 for a portable terminal comprises an antenna element part 2 in which a second tubular antenna element 22 is internally mounted in a first tubular antenna element 21 in such a manner as to be capable of protruding or receding, a holding part 3 for holding the antenna element part 2, and a contact conduction part 4 that is provided on the downside of the holding part 3. In the antenna 1, a sleeve 224 is provided on the downside of a contact spring 221 provided around a leading end of the second tubular antenna element 22, and the contact spring 221 and the sleeve 224 are constantly and internally mounted in the first tubular antenna element 21. <P>COPYRIGHT: (C)2012,JPO&INPIT |
