A component for a hot-dip metal plating bath includes a base material and a thermal spray coating disposed to cover a surface of the base material. The base material includes ferritic stainless steel that contains: C: 0.10% to 0.50% by mass; Si: 0.01% to 4.00% by mass; Mn: 0.10% by mass to 3.00% by mass; Cr: 15.0% to 30.0% by mass; a total of Nb, V, Ti, and Ta: 0.9% by mass to 5.0% by mass; and a balance of Fe and unavoidable impurities. The ferritic stainless steel includes a microstructure that includes a ferrite phase as a main phase and a crystallized carbide, an area fraction of a Nb carbide, a Ti carbide, a V carbide, a Ta carbide, and a composite carbide thereof to the crystallized carbide of 30% or more. The hot-dip metal plating bath contains 50% by mass or more of Al.
