Method for manufacturing hot-forged member

Provided is a method for manufacturing a hot-forged member, the method enabling efficient hot forging while preventing defects such as cracks even if a hard-to-work alloy is used as a hot forging material. The method for manufacturing a hot-forged member comprises: a heating step in which an unheated material to be hot-forged is heated to a hot forging temperature in a heating furnace; a heat-resistant insulation bonding step in which heat-resistant insulation is bonded to at least a portion of the surface of the forging material, which has been removed from the heating furnace, to create a hot forging material; and a hot forging step in which any of a mold, an anvil, and a tool is used to compress and mold some or all of the hot forging material into a prescribed shape.
