Coil apparatus and manufacturing method for the same

摘要

In order to prevent a substrate for mounting electronic components from being damaged when cores are rubbed together during assembly, a pair of core members are respectively arranged so as to sandwich a part of a coil pattern formed on the substrate from the top and bottom sides of the substrate, and the core members are held together by a core-combining member. A cover member is arranged and fixed to the substrate so as to cover the upper side of the core-combining member. Inclined ribs on the cover member raise the core-combining member by abutting against external inclined faces of leg portions of the core-combining member so as to apply a raising force. A clearance thereby is formed between internal faces of a top bar portion of each core member and a surface of the substrate. When sliding the core member, the surface of the substrate is not contacted by the core member so as not to be damaged.
