A method for producing a hot rolled electrical steel sheet excellent in magnetic characteristics and corrosion resistance, characterized in that the method comprises providing heating a super high purity iron having the composition: Fe: 99.95 mass % or more, C + N + S: 10 mass ppm or less, O: 50 mass ppm or less, and balance: inevitable impurities, heating the iron to th e .gamma. region thereof, carrying out a hot rolling at the .gamma. region und er a condition wherein a total draft is 50 % or more and the friction coefficie nt between a roll and a rolled material is 0.3 or less at least in one pass, an d then cooling the rolled iron under a condition wherein the average cooling speed in the range of Ar3 transformation point to 300~C is 0.5 to 150~C/min, thereby forming orientation grains having ~100~ axes integrated to the direction perpendicular to a sheet plane.
