Abstract
é fornecida uma chapa de aço elétrico com grão orientado que inclui uma chapa de aço tendo uma superfície de chapa de aço em que uma ranhura, que se estende em uma direção que cruza uma direção de laminação e cuja uma direção de profundidade de ranhura corresponde a uma direção de espessura de chapa, é formada. em um caso em que a superfície de chapa de aço é observada a partir da direção de espessura de chapa, a superfície de chapa de aço é dotada de um grupo de ranhuras que é constituído por uma pluralidade das ranhuras disposta em uma direção de largura da chapa, as ranhuras, que constituem o grupo de ranhuras, são dispostas de modo que as ranhuras adjacentes se sobreponham umas às outras em um plano de projeção perpendicular à direção de laminação, e uma pluralidade de grupos de ranhuras fica disposta com um intervalo na direção de laminação.
