Abstract

　本発明に従い、鋼板面内の圧延方向に対して60°から120°の方向に、圧延方向の間隔がｓ（mm）にて周期的に形成され、線状に広がった還流磁区領域を有し、実測板厚：ｔ（mm）である方向性電磁鋼板において、上記還流磁区領域の深さ：ｈ（μm）および幅：ｗ（μm）を、ｈ≧74.9ｔ＋39.1 （0.26≧ｔ）、ｈ≧897ｔ－174.7 (ｔ＞0.26）、（ｗ×ｈ）／（ｓ×1000）≦－12.6ｔ＋7.9 (ｔ＞0.22）、（ｗ×ｈ）／（ｓ×1000）≦－40.6ｔ＋14.1 (ｔ≦0.22)の関係をそれぞれ満足させる範囲とすることによって、幅広い板厚範囲において低鉄損化した方向性電磁鋼板を得ることができる。
