Summary:PROBLEM TO BE SOLVED: To provide a laminate core capable of solving a problem occurring when an insulating film contains phosphate or chromate. SOLUTION: The laminate core 1 includes laminated electromagnetic steel plates 11, and insulating films 12 are formed between the electromagnetic steel plates 11 respectively. Since the insulating film 12 is made of at least any one of DLC (diamond-like carbon) and fullerene, it can be formed at a low temperature. A step of cooling the insulating film 12 can be remarkably reduced. Since the insulating film 12 contain no hazardous material, it is never limited in use from a view of environmental impact. Since the insulating film 12 has good heat conductivity, heat conduction in a laminate direction is good when a motor having a built-in laminate core is used. When the electromagnetic steel plate 11 is punched, punching processability is good. The insulating film 12 has good substrate followability. When an electromagnetic coil is wound around the laminate core 1, an insulating coating of the electromagnetic coil can be free from damage. COPYRIGHT: (C)2011,JPO&INPIT
