Abstract: A grain-oriented electrical steel sheet includes a steel sheet having a surface on which grooves in which an extending direction crosses a rolling direction and a depth direction is parallel to a sheet thickness direction are formed. A molten solidified substance ranging in parallel to the groove exists on both sides of the groove on a surface of the steel sheet. A height becoming a maximum frequency in a height distribution of height data in which the surface of the steel sheet in a specific area including the groove is measured at regular intervals is set as a virtual plane, and when a space volume of recess parts recessed from the virtual plane is set as V1 and a volume of projection parts projected from the virtual plane is set as V2, a value of V2/V1 is more than 0.10 and less than 0.80. A plurality of projections are formed in the specific area, and among the plurality of projections, a width of a projection closest to the groove is larger than widths of the other projections. When an area where an average height in the extending direction is highest in the height distribution is seen in a groove longitudinal cross section including the extending direction and the sheet thickness direction, an average roughness Ra of a roughness curve forming a surface of the area is 0.30 to 2.00 μm, and an average length RSm of a roughness curve element forming the surface of the area is 10 to 150 μm.
