Abstract

PROBLEM TO BE SOLVED: To surely receive radio waves even when a portable telephone set is horizontally set on a table or the like by making an antenna composed of a second connection fitting, which is attached so as to be perpendicularly bent, and a main body of antenna attached so as to be bent perpendicularly to the turning direction of this fitting. SOLUTION: A first connection fitting 5 is attached at the top end part of an antenna connection fitting 4 so as to perpendicularly turn a rear end part at least. A second connection fitting 6 is attached at the top end part of the first connection fitting 5 so as to turn a rear end part perpendicularly in the same direction as the turning direction of the first connection fitting 5 at least. A main body 7 of antenna is attached to the top end part of the second connection fitting 6 so as to be perpendicularly in the same direction as the turning direction of the second connection fitting 6 at least. When setting such a portable telephone set 2 on a table 32 or the like, since the portable telephone set 2 is placed horizontally, the state capable of surely receiving radio waves is provided in the state of turning the main body 7 of antenna about at 90 deg. and protruding the extended antenna upward.
