PROBLEM TO BE SOLVED: To provide a stacked iron core which can realize high efficiency, high output, and energy saving of a motor, a transformer, etc., or can downsize them and is superior in magnetic property and is superior in stacking form, by fully utilizing an amorphous thin plate. SOLUTION: In the stacked iron core which is constituted by stacking amorphous iron core pieces, metal plate iron core pieces 2 are provided dispersedly under, between, or above plural sheets of amorphous iron core pieces piled up continuously, and an opening 8 for caulking is made in the lower metal plate iron core piece 2a, and a calking projection 9 made at another metal plate iron core piece 2 described above engages with the opening 8 for caulking of the above lower metal plate iron core piece 2a or a recess 10 behind the caulking projection of the metal plate iron core piece 2 in the next lower layer, passing through a bored hole 7 for calking made in each of amorphous iron core pieces 3, being stacked continuously in plural numbers, thereby caulking the amorphous iron core piece 3.
