PROBLEM TO BE SOLVED: To provide a laminated core of heterogeneous material formed by making the most of a characteristic of material for a core piece, for instance, from a laminated plate of heterogeneous material including amorphous, having a large calking strength of the punched core piece even by thinning the respective material for the core piece, superior form strength, further with various superior of electromagnetic characteristics or the like. SOLUTION: A laminated plate 29 of heterogeneous material is formed by interposing a high magnetic material 32 of difficult workability with workability inferior from a plate material 30, 31 in the upper/lower side, stacked core pieces 23 to 26 of heterogeneous material punched from the stacked plate 29 of heterogeneous material are stacked to a desired stacked thickness via calking parts 27, 28 formed with a notched hole 40, 41 in the center to be formed by cutting down both sides in the lengthwise direction of the notched hole 40, 41.
