Claims15
A device comprising:
- a core;
- a first winding portion that turns around an outer circumference of the core;
- a plurality of sub-substrates each having a pattern of a second winding turning around the outer circumference of the core;
- and
- a main substrate on which the plurality of sub-substrates are mounted,
- wherein
- the plurality of sub-substrates are mounted on the main substrate to be in parallel to each other,
- each of the plurality of sub-substrates has a through hole into which a magnetic core portion of the core is inserted,
- the pattern of the second winding turns around the through hole on each of the plurality of sub-substrates,
- a plurality of the first winding portions each of which is arranged between different sub-substrates out of the plurality of sub-substrates, and
- the sub-substrate out of the plurality of sub-substrates that contacts the first winding portion has the pattern of the second winding only in an inner layer on a surface side contacting the first winding portion.
