PROBLEM TO BE SOLVED: To accurately match the sending amount of blood or blood components with a target sending amount. SOLUTION: A blood component collection device 10 is provided with a donor pressure sensor 38 for detecting the donor pressure Pd of a blood collection line, a variable speed blood pump 28 for sending the blood components in the blood collection line and a treating circuit, and a pump speed control part 98 for obtaining a blood pump speed command R1 by dividing the target sending amount Q1c of the blood pump 28 by a basis sending amount K1 per unit rotation of the blood pump 28 and driving the blood pump 28 so as to be driven according to the blood pump speed command R1. The pump speed control part 98 refers to blood collection time-basis sending amount correction data 98a on the basis of the donor pressure Pd, corrects the basis sending amount K1 and obtains the blood pump speed command R1.
