WIRE-WOUND COIL

PROBLEM TO BE SOLVED: To provide a wire-wound coil which has a structure to be able to suppress an influence on a floating capacity due to a magnetic material core. SOLUTION: Each winding of 37 and 47 is wound as a single layer on outer peripheries of tubular cylinder portions 33 and 43 of bobbins 32 and 42. A space gap G1 with a prescribed dimension of (0.3 to 1.5 mm) is formed between inner wall faces of holes 33a and 43a of the tubular cylinder portions 33 and 43 of the bobbins 32 and 42 and outer peripheral faces 52aa and 52ba of leg portions 52a and 52b of core members 50a and 50b. A space gap G2 with a prescribed dimension of (0.7 to 4.0 mm) is formed between inside faces 51aa and 51bb of arm portions 51a and 51b of the core members 50a and 50b and outside main faces 34a, 35a, 44a and 45a of each flange portion of 34, 35, 44 and 45 of the bobbins 32 and 42.
