PROBLEM TO BE SOLVED: To provide a method for forming a hardfaced layer, which suppresses occurrence of cracks in the hardfaced layer. SOLUTION: The method for forming a hardfaced layer comprises: a step of forming a molten pool 8 on a base material 4 by melting a welding wire 7 as a filler material; a step of feeding hard particles 2, which contain first particles consisting of materials having specific gravity smaller than that of the filler material, to the molten pool 8; and a step of obtaining a hardfaced layer 3, which is formed on the base material 4 by solidifying the molten pool 8 and contains the hard particles 2 in an unmolten state.
