Abstract: Provided are a manufacturing device and a manufacturing method for a laminated iron core, which are capable of more easily assembling an adhesive application means and shortening a time required for maintenance. A manufacturing device 1 for a laminated iron core 4 according to the present invention includes: an adhesive application means 6 for applying an adhesive to a region corresponding to an iron core thin plate 3 of a steel plate 2; a forward/backward drive unit 7 for switching whether or not to perform application of the adhesive by the adhesive application means 6; and a buffer member 8 for allowing displacement of the adhesive application means 6 in a forward/backward direction. The adhesive application means 6 has a discharge unit 60 configured to discharge the adhesive from the tip of the passage 60a. The adhesive application means 6 is disposed so that, when the adhesive is applied, the adhesive discharged from the tip of the discharge unit 60 is brought into contact with the steel plate 2 according to the vertical movement of the steel plate 2 in association with the punching formation of the iron core thin plate 3 from the steel plate 2. The adhesive application means 6 is configured so that the contact pressure of the tip to the steel plate 2 is adjusted by the buffer member 8.
