PROBLEM TO BE SOLVED: To provide a laminated iron core having a high iron loss characteristic and a method for manufacturing the laminated iron core. SOLUTION: In the laminated iron core formed by laminating unit iron cores each of which is punched as a prescribed shape and partially fixing the surfaces of the unit iron cores by using an adhesive, the adhesive application positions of respective unit iron cores are arranged on respectively different positions in the lamination direction. The adhesive application positions are arranged on respectively different positions in each prescribed number of units and a thermosetting adhesive or inorganic adhesive is used as the adhesive. While partially fixing the unit iron cores by the adhesive, the fixing positions are made different in each unit iron core. Consequently the iron core having high iron loss characteristic and lamination accuracy can be obtained. COPYRIGHT: (C)2004,JPO
