Abstract
A structural memberhas a base materialand a protective filmcovering the surface Sof the base material. When a section obtained by cutting the base materialperpendicularly to the surface Sthereof is defined as a cross-section, a shape of a line corresponding to the surface Sof the base materialin the cross-section is defined as a surface shape, and Fourier transformation is performed on a function representing the surface shape, and the transformed function is drawn as a graph with wavelength (μm) on a horizontal axis, an average slope of the graph in a range where the wavelength is 30 μm or less is 0.0050 or less.
