Abstract: The present invention relates to a method for manufacturing an inner structure of a regenerative cooling type combustion chamber, and more specifically to a method for manufacturing the inner structure of the regenerative cooling type combustion chamber, including the steps of: manufacturing a cylinder structure by performing a vacuum casting process or an air casting process for a copper alloy; manufacturing a circular plate having a constant thickness by forging and rolling the cylinder structure; thermally and mechanically processing the circular plate; spinning the circular plate to manufacture the shape of the regenerative cooling type combustion chamber; and thermally processing the shape of the regenerative cooling type combustion chamber. The method for manufacturing the inner structure of the regenerative cooling type combustion chamber can prevent necking and damage of the structure and can improve reliability during a bulging process for assembling the inner structure with an outer structure of the combustion chamber by uniformizing and miniaturizing the grain size of the inner structure of the combustion chamber.
