<p><P>PROBLEM TO BE SOLVED: To reduce cost, with respect to a core combination member of a coil device. <P>SOLUTION: In the coil device having a pair of core members 4a, 4b, equipped on a coil pattern under a configuration of pinching at least one part of a coil pattern formed on the circuit substrate 2 from both front and rear sides of the circuit board 2, and a core combination member 20 for combining the core members 4a, 4b, the core combination member 20 is provided with a leg unit 22, penetrated through the core leg by a through hole 6 of the circuit substrate 2. Since the core combination member 20 can combine the core members 4a, 4b by a single component, whereby the cost can be saved, as compared with a case when two components are employed. The adjustment of the cores can be effected, under the condition where the core members 4a, 4b are combined through a cutting and removing part 25 for the clearance of the leg unit 22, as it is. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
