Winding Iron Core, Method For Manufacturing Winding Iron Core, And Winding Iron Core Manufacturing Apparatus

Abstract: This winding iron core (10) is characterized by being formed by including a part in which directional electrical steel sheets (1) in which flat surface parts (4) and bent parts (5) are alternately continuous in a longitudinal direction are stacked in a plate thickness direction, by stacking individually bent directional electrical steel sheets (1) in layer shapes, and by assembling the directional electrical steel sheets (1) into a winding shape, wherein, when the average height of roughness curve elements in a width direction intersecting the longitudinal direction in which the surfaces of the bent parts (5) of the directional electrical steel sheet (1) are formed is Ra(b), and when the average height of the roughness curve elements in the width direction in which the surfaces of the flat surface parts (4) of the directional electrical steel sheet (1) are formed is Ra(s), the relationship 1.00
