PROBLEM TO BE SOLVED: To provide a helical antenna having a structure capable of easily fixing a helically wound conductor inside a cover. SOLUTION: The helical antenna includes the helically wound conductor 1, a power feeding connector 3, and the cover 2 for covering the conductor 1. A non-woven fabric 15 is arranged between the tip end of the helical conductor 1 and the cover 2. The conductor 1 is pressurized against the inner wall of the cover 2 by the elasticity of the non-woven fabric 15, so as to fix the conductor 1 and the cover 2. A support 4 is arranged in the power feeling connector 3 so as to fix the support 4 to the open end of the cover 2 by fitting. COPYRIGHT: (C)2007,JPO&INPIT
