ABSTRACT:
A very small and thin transformer to be used as incorporated in an electronic device for the civil life. In this transformer, a coil is wound on a coil bobbin in which core sheets are incorporated as laminated. This laminated core is provided with an insulating cover for insulation. However, when a gap is produced between the core sheets, an adverse influence will be produced on the electric characteristics of the transformer. Therefore, in case the insulating cover is applied to cover the laminated core, the insulating cover having a resiliency will press the core sheets in the laminating direction to prevent a gap from being produced between the core laminations.
