PROBLEM TO BE SOLVED: To provide a high frequency coil of the structure which is covered with a shield case with less drop of the Q. SOLUTION: Under the condition that the coil winding start side 4 and the coil winding end side 5 of a material coil 2 are laid at the area near the external circumference of a coreless coil 3 formed by winding the material coil 2 like a solenoid, a resin-molded base formed by embedding such material coil is also provided. A projected part 7 for embedding the coil winding start side 4 and the coil winding end side 5 of the material coil 2 with resin-molding and a concave part engaged with the projected part 7 are provided. Moreover, a cap core 8 covering the coreless coil 3 and projected part 7 and a metal case 9 covering the base 6 and coreless coil 7 covered with the cap core 8 from the side of cap core 8 are also provided.
