摘要： An iron core-producing method of the invention includes at least the step of blanking an iron core T from a strip W in such a manner that a longitudinal direction of the substantially linear iron core T is inclined relative to a direction of a width of the strip W. An iron core-producing apparatus of the invention for blanking a substantially linear iron core T from a strip W includes at least a punch disposed such that its longitudinal direction is inclined relative to a direction of a width of the strip W, and a die 13 which is provided beneath the punch, and is disposed such that its longitudinal direction is inclined relative to the direction of the width of the strip W.
