PURPOSE: A mold for hydro-forming of a closed-member and a method for manufacturing integration parts using the same, and an integration part are provided to prevent the fault of molding due to the leakage of fluid pressure. CONSTITUTION: A mold for hydro-forming of a closed-member comprises an upper mold(310) and a lower mold(320). A protrusion(330) is comprised in one of the upper mold and the lower mold. The protrusion applies hydraulic pressure to materials. A fluid pressure applying path(350) is formed in the mold and connected to the fluid pressure applying hole(h) formed in the materials. An additional sealing member(332) is installed around the protrusion.
