Summary:According to an embodiment, a method for manufacturing a joined metal member includes: disposing a first metal member inside a mold of an injection molding apparatus, the first metal member being made of a first metal material, unevenness being formed over a surface of the first metal member, and an oxide film being formed so as to cover the unevenness; and injecting a second metal material into the mold, and thereby molding a second metal member and joining the second metal member to the first metal member, the second metal material being, when it is injected into the mold, in a semi-molten state, or in a molten state in which a difference between a temperature of the second metal material and a liquidus temperature thereof is smaller than or equal to 30° C.
