This grain-oriented electrical steel sheet has an aggregate structure oriented in the Goss orientation, and the angles of deviation of the crystal orientation measured at two measuring points adjacent on the plate surface and having a spacing of 1 mm are (α 1 β 1 γ 1 ) and (α 2 β). 2 γ 2 ), the boundary condition BA is defined as |γ 2 -γ 1 |≥0.5°, and the boundary condition BB is [(α 2 -α 1 ) 2 +(β 2 -β 1 ) 2 +(γ) 2 -γ 1 ) 2 ] 1/2 When defined as ≥2.0°, there exists a grain boundary that satisfies the boundary condition BA and does not satisfy the boundary condition BB.
