PROBLEM TO BE SOLVED: To provide a lubrication binder for low-density powder metallurgy, which gives a low rattler value to a powder without worsening its lubricity and provides a green compact free from cracking, chipping and density unbalance; a method for manufacturing the lubrication binder for the low-density powder metallurgy; and a method for manufacturing an adequate product obtained by low-density powder metallurgy through the green compact free from the cracking, chipping and density unbalance, as a result of having given the low rattler value to the powder. SOLUTION: The lubrication binder for the low-density powder metallurgy is a molten mixture of the binder for the powder metallurgy and a lubricant for the powder metallurgy, and consists of particles with a median diameter of 5 to 70μm.
