PROBLEM TO BE SOLVED: To provide a method for forming a hardfaced layer, which suppresses occurrence of cracks in the hardfaced layer and further improves wear resistance. SOLUTION: The method for forming a hardfaced layer comprises: a step S1 of forming a molten pool on a base material by melting a filler metal made of carbon steel; a step S2 of feeding hard particles, which contain carbide or carbonitride, to the molten pool; and a step S3 of obtaining a hardfaced layer, which is formed on the base material by solidifying the molten pool and contains the hard particles, part of which are melted, in an unmolten state; and a step S4 of quenching the base material and the hardfaced layer.
