PURPOSE:To improve assembling-work efficiency and economization without lowering the performance, by changing one-time laminated number of iron core materials in accordance with the positions of spaced members. CONSTITUTION:Electromagnetic force acting on flat plate coils 1, as long as insulating plates 2 between coils and cores are not large enough in both thickness and rigidity, is conveyed to only the range of iron cores facing the spaced members 3 and is not actuated on mutual parts between the spaced members 3. The positions of the spaced members 3, which are to be positioned on the coil surface sides, are beforehand scribed on the insulating plates 2 facing the iron core surface and existing on both sides of the iron core, on the stage of parts-production, one-time laminated number is changed with those scribing lines to be used as marks, for laminating iron-core materials for changing the number of laminates. The one-time laminating number is decreased only on the position where the force is essentially conveyed and frictional force is necessitated, and on the other hand the one-time laminating number is increased at the parts not facing the spaced members 3, to the range which is allowable to magnetic characteristics, to improve assembling-work efficiency.
