A spray coating containing a rare earth fluoride and/or a rare earth acid fluoride contains, carbon at 0.01-2% by mass or titanium or molybdenum at 1-1000 ppm. When an acid fluoride is not contained, the spray coating is gray to black in which, in terms of the L*a*b* chromaticity, L* is 25-64, a* is 3.0 to +5.0, and b* is 4.0 to +8.0. When an acid fluoride is contained, the spray coating is white or gray to black in which, in terms of the L*a*b* chromaticity, L* is equal to or greater than 25 and less than 91, a* is 3.0 to +5.0, and b* is 6.0 to +8.0. By forming this coating on a plasma resistant member, a partial color change is reduced, thus, a member that is capable of reliably realizing the original longevity is obtained.
