A flare nut (FN; 1A) is provided with a resin coating layer (18; 28) that includes a polyethylene based substance, a lubricant, and solid particles. When mass per unit area w (g/m2) is defined as a value obtained by dividing the mass difference between a state with the resin coating layer (18; 28) and a state without the resin coating layer (18; 28) by the surface area of a coated region (R), the mass per unit area w satisfies a relation 0.79",
