Abstract: An Fe-based amorphous alloy ribbon reduced in an iron loss in a condition of a magnetic flux density of 1.45 T is provided. One aspect of the present disclosure provides an Fe-based amorphous alloy ribbon. The Fe-based amorphous alloy ribbon has continuous linear laser irradiation marks on at least one surface. The linear laser irradiation marks are formed along a direction orthogonal to a casting direction of the Fe-based amorphous alloy ribbon. Each linear laser irradiation mark has unevenness on its surface. When the unevenness is evaluated in the casting direction, a difference HL between a highest point and a lowest point in the thickness direction of the Fe-based amorphous alloy ribbon is 0.25 μm to 2.0 μm.
