Claim 12:
13. The grain oriented electrical steel sheet according to claim 12, wherein
when a grain size RCL is defined as an average grain size obtained based on the boundary condition BC in the rolling direction L,
a grain size RBL is defined as an average grain size obtained based on the boundary condition BB in the rolling direction L,
a grain size RCC is defined as an average grain size obtained based on the boundary condition BC in the transverse direction C, and
a grain size RBC is defined as an average grain size obtained based on the boundary condition BB in the transverse direction C,
the grain size RCL, the grain size RCC, the grain size RBL, and the grain size RBC satisfy (RBC×RCL)÷(RBL×RCC)<1.0.
