Electrical steel sheet
An electrical steel sheet (1) includes a base material (2) of electrical steel, and an insulating film (3) formed on a surface of the base material (2), the insulating film (3) containing a polyvalent metal phosphate and Fe. A maximum value of a parameter Q expressed by “Q=CFe—O/CP” is equal to or less than 1.3 times and equal to or more than 1.09 times an average value of the parameter Q in a region from a first depth from a surface of the insulating film to a second depth, CFe—O denoting a proportion (atom %) of Fe bonded to O relative to all elements, and CP denoting a proportion (atom %) of P relative to all elements. The first depth is 20 nm from the surface, and the second depth is a depth where the proportion of P is equal to a proportion of metal Fe.
