    Abstract: This invention provides an electromagnetic steel sheet, which, after lamination, can be bonded by pressing and heating, can realize strain relieving annealing, and has a surface covered with a heat resistant adhesive insulating film, an iron core using the electromagnetic steel sheet, and a process for manufacturing the same. The electromagnetic steel sheet is covered with a heat resistant adhesive insulating film comprising a resin, which softens at room temperature or above and 300°C or below, and a low-melting inorganic component having a softening temperature of 1000°C or below as measured by a differential thermal analysis method. A strain relieving annealable bonded fixed iron core is provided by stacking this electromagnetic steel sheet and conducting press fixation.
