Abstract
A split-type laminated iron core is composed by laminating a plurality of metal plate materials having an annular shape. The metal plate material includes a first split piece and a second split piece arranged in a circumferential direction and divided by a predetermined cutting line. A shear surface formed on a first end surface of the first split piece and a shear surface formed on a second end surface of the second split piece abut on each other, and the first split piece and the second split piece are temporarily connected via the cutting line defined by a boundary between the first end surface and the second end surface so that the first end surface and the second end surface do not completely overlap.
