To prevent an adhesive agent from adhering to a die set for outer shape punching and avoid contamination of the die set by the adhesive agent even if the adhesive agent protrudes from the outer shape contour of a laminated iron core, a laminated iron core manufacturing device includes: a first punch (32) and a first die (48) for punching a part of an outer shape of each iron core lamina in a sheet steel strip; an adhesive agent applying apparatus (60) configured to apply an adhesive agent on an adhesive agent application region including a portion defined in the sheet steel strip by punching by the first punch (32) and the first die 48; and a second punch (34) and a second die (50) configured to punch the outer shape of each iron core lamina other than the part punched by the first punch (32) and the first die (48) from the sheet steel strip.
