Abstract
An electromagnetic induction device having a flat configuration that requires a relatively small space for installation on a circuit substrate includes a flat bobbin ( T) having a length (D ) smaller than a radial size (D ) thereof has primary and secondary windings ( ) wound thereon. This bobbin ( T) has coaxially aligned throughholes ( ) defined therein into which core legs ( T and T) of generally T-shaped first and second core pieces ( T, T) are inserted from opposite directions, respectively. Respective core arms ( T, T) of the first and second core pieces ( T, T) extend parallel to each other.
