The invention discloses an aluminum alloy sacrificial anode for a deep sea environment and a manufacturing method of the aluminum alloy sacrificial anode. The manufacturing method comprises the following steps that raw materials are weighed according to the proportion that Al-Zn (4.95-5.35), In (0.017-0.018) and Si (0.08-0.09); the furnace temperature is set to be 720-730 DEG C, and aluminum, aluminum-silicon alloy, zinc and indium are sequentially put into the raw materials so that the raw materials can be completely molten; keeping the temperature of the melt at 720-730 DEG C, standing for 10 minutes, degassing and removing scum; the cast iron mold is heated to 350-400 DEG C; the melt is stirred again for 10 min, and casting is started after standing is conducted for 5 min; and keeping the alloy in a constant-temperature mold for 5-30 minutes, taking out the alloy, and cooling the alloy to room temperature from an air hole. The expected metal structure and electrochemical performance ...
