Abstract
An electrical steel sheet includes: a specific chemical composition; a crystal grain diameter of 20 μm to 300 μm; and a texture satisfying Expression 1, Expression 2, and Expression 3 when the accumulation degree of the (001)[100] orientation is represented as ICube and the accumulation degree of the (011)[100] orientation is represented as IGoss. IGoss+ICube≥10.5 Expression 1 IGoss/ICube≥0.50 Expression 2 ICube≥2.5 Expression 3
