Abstract: A corrosion-resistant member including: a metal base material (10); and a corrosion-resistant coating (30) formed on the surface of the base material (10). The corrosion-resistant coating (30) is a stack of a magnesium fluoride layer (31) and an aluminum fluoride layer (32) in order from the base material (10) side. The aluminum fluoride layer (32) has a first crystalline region (32A) and a second crystalline region (32B) containing crystalline aluminum fluoride. The first crystalline region (32A) is a region in which diffraction spot arrays having regularity are observed in an electron beam diffraction image obtained by irradiation with electron beams having a beam diameter of 10 nm to 20 nm. The second crystalline region (32B) is a region in which a plurality of diffraction spots is observed but diffraction spot arrays having regularity are not observed in an electron beam diffraction image obtained by irradiation with the above-described electron beams.
