<p><P>PROBLEM TO BE SOLVED: To provide an antenna in which a bent provided to an element is inserted into a notch formed by cutting off a pair of linkage crosspieces formed when a circuit board is formed, and both are favorably combined. <P>SOLUTION: When individual circuit boards 1 are processed so that the adjacent circuit boards are connected at their frames 60 by a pair of right-side linkage crosspieces 62, a recess 81 is provided in each linkage crosspiece 62 to be recessed inwardly of the width direction of the crosspiece from its width-directional end, and thereafter a fourth notch 7 is formed by cutting the right-side linkage crosspiece 62 at a position including the recess 81, and parts of the recesses 81 form a chamfering shape 71 located at a tip end of an opening. For this reason, generation of a whisker extended from the cut location toward the interior of the fourth notch 7 is suppressed, whereby a third bent 45 of a right-side element 41 is favorably inserted. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
