PROBLEM TO BE SOLVED: To prevent short circuit between windings or between the winding and a board terminal or board pads due to cream solder. SOLUTION: The antenna is provided with a metallic winding 13 which is wound around the peripheral surface of a ferrite core 11 while the winding being exposed and has an insulation coating on its surface, and printed board connection terminals 18 to which soldering pads 19 of the printed board 20 are connected via the cream solders 21 and connection terminals 15 are connected, wherein a shielding body 23 for preventing the cream solders 21 from flowing into the winding 13 is formed between the terminals 18 and the winding 13. With this constitution, since the cream solders 21 can be prevented from flowing into the winding 13 side by the shielding body 23 provided between the terminals 18 and the windings 13, short circuit hardly occurs between the windings 13 or between the winding 13 and the terminals 18 or board pads 19 due to the cream solders 21.
