A grain oriented electrical steel sheet includes the texture aligned with Goss orientation. In the grain oriented electrical steel sheet, when (αβγ) and (αβγ) represent deviation angles of crystal orientations measured at two measurement points which are adjacent on the sheet surface and which have an interval of 1 mm, the boundary condition BA is defined as [(α−α)+(β−β)+(γ−γ)]≥0.5°, and the boundary condition BB is defined as [(α−α)+(β−β)+(γ−γ)]≥2.0°, the boundary which satisfies the boundary condition BA and which does not satisfy the boundary condition BB is included.
