Abstract
Provided is a structural member in which adhesion between the pre-coat layer and the protective film can be enhanced, while the time required to form the pre-coat layer is reduced. The structural member 10 includes a base material 100 and a protective film 200 covering the surface 101 of the base material 100. The protective film 200 includes, as a main component, yttria with an oxygen content lower than the stoichiometric ratio, and the arithmetic mean roughness of the surface of the protective film 200 is 0.65 μm or less.
