PROBLEM TO BE SOLVED: To manufacture a laminated iron core, which is constituted by stacking iron core pieces struck from an amorphous thin plate and where the iron core pieces are unified strongly without space and which is excellent in stacking form and is making the most of magnetic property specific to the amorphous thin plate. SOLUTION: In the method of manufacturing the amorphous laminated iron core by striking the iron core pieces from the amorphous thin plate material and stacking them, a required place for each iron core piece is struck from the amorphous thin plate material so as to make each iron core piece, and a coupling hole 12 is made, and each iron core piece is stamped out externally by a die hole, and a plurality of iron core pieces are stacked into a specified thickness on a receiving block 20 which faces the above die hole from below and can freely advance and retreat, and then the above receiving block 20 is retreated from the die hole, and the stacked iron core pieces 17 stacked on that receiving block 20 are held and bound together, and the coupling holes 12 of those stacked iron core pieces 17 are charged with bond, thereby coupling the iron core pieces together.
