WINDING-TYPE COIL

PROBLEM TO BE SOLVED: To provide a winding-type coil having a structure that an effect on floating capacitance due to a magnetic core is controlled. SOLUTION: Each of windings 37, 47 are wound around circumferences of cylindrical bodies 33, 43 of bobbins 32, 42 in a single layer. Rail-like protrusions 33b, 43b are formed on inside wall surface of holes 33a, 43a of the cylindrical bodies 33, 43 of the bobbins 32, 42, thereby, air gaps G1 are formed between the inside wall surfaces of the holes 33a, 43a and circumferential surfaces 52aa, 52ba of leg portions 52a, 52b of core components 50a, 50b. Protruded spacers 36, 46 are disposed on outside main surfaces 34a, 35a, 44a, and 45a of each of flange portions 34, 35, 44, and 45 of the bobbins 32, 42, thereby, air gaps G2 are formed between inside surfaces 51aa, 51bb of arm portions 51a, 51b of the core components 50a, 50b and the outside main surfaces 34a, 35a, 44a, and 45a.
