PURPOSE: To completely prevent a blood bag from being punctured in the case of a centrifugal separation processing and to obtain the blood bag with the satisfactory disentangled state of blood platelets by forming a projecting part on the inside of a bag-shaped main body and forming a blood housing room over the upper and lower sides of an extension line in the tip of the projecting part.
CONSTITUTION: On the inside of a main body 2, a thick projecting part 12 is formed and over the upper and lower sides of an extension line 0 in the tip of the projecting part 12, a space is spread to form a blood housing room 13. The projecting part 12 is formed while setting width W1 in the range of 0.6mm to 1.2mm and setting thickness D1 in the range of 0.8mm to 1.4mm. The width W1 and the thickness D1 is gradually formed to be large from 0.6mm to 1.2mm toward a bottom part B in the range of a size and the thickness D1 is also gradually formed to be large from 0.8mm to 1.4mm from a side part S to a corner part R and the bottom part B.
