Abstract: Provided are a laminated iron core manufacturing apparatus and manufacturing method that make it possible to more reliably separate a laminated iron core from an iron core thin plate group and to increase the speed at which the iron core thin plates are punched. A laminated iron core 4 manufacturing apparatus 1 according to the present invention is for manufacturing a laminated iron core 4 obtained by punching and forming iron core thin plates 3 having a prescribed shape from a steel plate 2 and laminating and bonding a prescribed number of the iron core thin plates 3. The manufacturing apparatus 1 comprises: a punching part 5 for punching the iron core thin plates 3 from the steel plate 2; an adhesive application part 6 for applying an adhesive to sites corresponding to the iron core thin plates 3 of the steel plate 2; a lamination part 7 for forming an iron core thin plate group 30 by laminating and adhering the iron core thin plates 3 in a state in which the adhesive is applied; and a separation part 8 that bites between iron core thin plates 3 adjacent to each other in the iron core thin plate group 30 and separates the laminated iron core 4 from the iron core thin plate group 30. The lamination part 7 has a plurality of pairs of lateral pressure application parts 71 that apply lateral pressure to the iron core thin plate group 30, each pair of lateral pressure application parts 71 are arranged so as to face each other with the iron core thin plate group 30 interposed therebetween, and at least one of the lateral pressure application parts 71 also serves as the separation part.
