PROBLEM TO BE SOLVED: To provide a manufacturing method of a stacked body whose warping is suppressed or prevented and which has high heat resistance, to provide a steel heater having the stacked body, and to provide an LED light emitting body. SOLUTION: The manufacturing method of the stacked body according to the present invention is a manufacturing method of a stacked body having a stainless steel sheet 11 and two or more glass layers (12) provided on one surface side thereof, the manufacturing method including: forming a non-fired glass layer 121a on one surface of the stainless steel sheet; then forming a glass layer 12a by firing the stainless steel sheet in a state wherein the other surface of the stainless steel sheet is brought into contact with a flat support; and firing the glass layer above the first glass layer in a state wherein both lengthwise end sides of the other surface of the stainless steel sheet are supported by an end support 21 after an intermediate stacked body curves so that the lower glass layer becomes convex.
