PROBLEM TO BE SOLVED: To reduce processes and costs for manufacturing and to reduce a size and thickness by omitting labor required for coiling and working and material costs required for installing leads after improving a surface mounting property as for a magnetic component used as a coil component or a transformer component. SOLUTION: A magnetic core 3 is arranged along the lower side substrate surface 2a of an insulating substrate 2, and a plurality of recessed conductors 4 are mounted to the insulating substrate 2 so as to extend across a magnetic path of the magnetic core 3. The conductors 4 have plane bottoms 4a, and are connected electrically through a wiring layer 5 formed on an upper side substrate surface 2b. At least two of a plurality of the conductors 4 function as connection terminals to a surface mounting substrate. COPYRIGHT: (C)2004,JPO
