PURPOSE: A method for manufacturing an oxide dispersion strengthened platinum material using a cross-roll is provided to increase grain texture extended in a specific direction. CONSTITUTION: A method for manufacturing an oxide dispersion strengthened platinum material using a cross-roll comprises the steps of: adding an alloy element to platinum to obtain ingot(S1), making the ingot into platinum alloy powder using plasma(S2), making preform through pressureless heat treatment of the platinum alloy powder(S3), internally oxidizing the preform through a queuing process(S4), increasing the density of the preform through high-pressure molding(S5), and obtaining a sintered body through hot working, cross-rolling, and final heat treatment(S6).
