Provided is a method for producing platelets, in which damage to platelets is suppressed compared with a method in which platelets are separated using a filter from a megakaryocyte culture, and then the platelets are concentrated using a hollow fiber membrane and are further washed using the hollow fiber membrane, and purified platelets can be produced in a shorter period of time compared with the time that is taken to perform the above-described method so as to reduce damage to platelets. The method for producing purified platelets of the present invention includes a concentrating step of concentrating a megakaryocyte culture, and a centrifuging step of centrifuging platelets from an obtained concentrate.
