An iron core () for a stationary induction apparatus according to one embodiment is configured by laminating a plurality of electromagnetic steel plates (). The electromagnetic steel plates are laminated so that joint parts (), at which the end portions of the electromagnetic steel plates abut one another, are disposed in a staggered manner; and the electromagnetic steel plates are provided with a magnetic domain fine differentiation processed part (), which is located on the portion, of a surface of the end portion of each of the electromagnetic steel plates, lapped with the joint part of another electromagnetic steel plate, and which has been subjected to warping-derived magnetic domain fine differentiation.
