1. A laminated iron core manufacturing apparatus for laminating a plurality of punched members obtained by punching a plate-shaped member, comprising:
a convey unit configured to convey the plate-shaped member;
a lifter configured to support the plate-shaped member conveyed by the convey unit;
a liquid material supply unit configured to adhere a liquid material to regions to be the punched members of one main surface of the plate-shaped member conveyed by the convey unit; and
a punching unit configured to punch the plate-shaped member after the liquid material is applied to form the punched members,
wherein the liquid material supply unit adheres the liquid material to the plate-shaped member while avoiding, in the regions to be the punched members in the plate-shaped member, a contact region where the lifter on a downstream side of an adhesion location of the liquid material in the liquid material supply unit and on an upstream side of the punching unit comes into contact with the plate-shaped member.
