Abstract

This galvanized steel sheet comprises a base steel sheet having a specified chemical composition, an Fe-Al alloy layer formed on at least a portion of the base steel sheet, and a zinc plating layer formed on the surface of the base steel sheet or the Fe-Al alloy layer, in which the base steel sheet has an internal oxide layer lying between the surface of the base steel sheet and a depth of 0.2 μm or more when observed in the thickness direction, the Fe-Al alloy layer has an average thickness of 1 nm or more and less than 100 nm, the tensile strength is 980 MPa to 2000 MPa inclusive, and, in a cross section in the thickness direction, the ratio of coating of a grain boundary with an oxide is 60% or more in the internal oxide layer and the ratio of coating of the aforementioned surface of the base steel sheet with the Fe-Al alloy layer is 40% or more.
