WIRE-WOUND COIL

PROBLEM TO BE SOLVED: To provide a wire-wound coil that can suppress the influence of a magnetic core upon the stray capacitance of the coil. SOLUTION: In this wire-wound coil, windings 37 and 47 are respectively wound in single layers around the cylindrical drum sections 33 and 43 of bobbins 32 and 42 and the bobbins 32 and 42 are mounted and fixed on a printed board 65 through lead terminals 54b and 55b, etc. In addition, a magnetic core 50 is mounted and fixed on the printed board 65 by means of a fastener 60. Moreover, spatial gaps G1 are respectively formed between the internal wall surfaces of the holes 33a and 43a of the cylindrical drum sections 33 and 43 of the bobbins 32 and 42 and the outer peripheral surfaces 52aa and 52ba of the leg sections of the magnetic core 50.
