PURPOSE: A coupling structure of laminated cores for a transformer is provided to be capable of being easily assembled and having excellent electrical characteristics and coupling strength as well as being supplied with a low cost. CONSTITUTION: The laminated cores(10,10') are formed by laminating a plurality of thin cores(11,11'). S-shape press-fit parts(13,13') are formed to be corresponding to each other on leading end outer parts of outer legs(12) of the upper thin core(11) and leading end inner parts of outer legs(12') of the lower thin core(11'). Further, embossing parts(14,14') for alignment and coupling of the cores are respectively formed on the thin cores(11,11'). The press-fit parts(13,13') are rigidly coupled when the cores(11,11') are inserted into a bobbin having a core wound.
