<p>PROBLEM TO BE SOLVED: To provide a laminated iron core which has a resin as a main constituent and is formed by connecting and joining respective iron core pieces and in which the joining strength of the iron core pieces provided at the end in the axial direction is increased, and also to provide a method of manufacturing the laminated iron core.SOLUTION: Disclosed is a laminated iron core 10 which is formed by laminating a plurality of iron core pieces 13, 14 and in which the respective iron core pieces 13, 14 are connected in the lamination direction by filling a plurality of resin holes penetrating through the laminated iron core 10 in the lamination direction with a resin. A joint area between an iron core piece (A) 13 provided at the end in the axial direction and the resin is made larger than that between an iron core piece (U) 14 arranged at the position other than the end in the axial direction and the resin or a lock hole is provided at the tip part of the resin, thereby securing the joint strength of the iron core piece (A) 13.</p> |
