ABSTRACT:
A thin type transformer has a coil bobbin with a coil wound on a flat and hollow barrel part of the bobbin, and a core mounted to the bobbin with a central leg portion of the core passed through the barrel part. Further, a pair of core cover members adapted to be mutually fittable while enclosing the core are mounted to the transformer as fitted and coupled to each other through engaging parts of the cover members, whereby constituent elements can be simplified while improving effectively the assembling and mass-producing ability.
