Abstract
Grain-oriented electrical steel sheet superior in core loss characteristic containing Si: 0.8 to 7 mass % and having a secondary recrystallized texture with a {110}<001> orientation as the main orientation, characterized in that average deviation angles α, β, and γ from the {110}<001> ideal orientation of the secondary recrystallized texture satisfy (α+β)≦γ, where α: average deviation angle from {110}<001> ideal orientation around rolling surface normal direction (ND) of secondary recrystallized texture, β: average deviation angle from {110}<001> ideal orientation around traverse direction (TD) of secondary recrystallized texture, and γ: average deviation angle from {110}<001> ideal orientation around rolling direction (RD) of secondary recrystallized texture.
