A vacuum blood collection tube which includes a tubular body with a bottom having inner spaces with a prescribed capacity and a plug body which hermetically seals an open end of the tubular body to maintain the inner spaces at a prescribed reduced pressure, wherein blood is collected into the inner spaces of the tubular body by differential pressure between the blood pressure and the pressure of the inner spaces via a hollow blood collection needle one end of which is punctured into a blood vessel and the other end of which is punctured into the plug body, the inner space is divided into a plurality of inner spaces by partitioning the inner space of the tubular body, each of the inner spaces has a prescribed capacity and maintains a prescribed reduced pressure depending on a purpose of each blood test, and the blood with an amount depending on the purposes of the various blood tests is collected in each of the inner spaces through the blood collection needle punctured into the blood vessel.
