PROBLEM TO BE SOLVED: To miniaturize an entire coil system. SOLUTION: In the formation of the coil system, a coil wire is wound and formed without using bobbins before setting into formation space 12 of a die, and the inside is filled with a molten resin, thus burying a unitary coil 1 into an armor body 2 without using any bobbins, reducing the size of the entire coil system by the thickness of the bobbin, and hence effectively utilizing the installation space for the coil system even if the installation space is limited.
