Abstract

Provided is a method for manufacturing a product, including a culture step of culturing cells in a culture solution accommodated in a tank, and a separation step of using a hollow fiber membrane filter which has a hollow fiber membrane having a primary flow passage extending in a longitudinal direction inside the hollow fiber membrane and has a housing accommodating a plurality of the hollow fiber membranes, the hollow fiber membrane filter having a secondary flow passage in a space of the housing outside each of the hollow fiber membranes, to feed the culture solution to the primary flow passage, and allowing a permeated liquid containing the product to permeate through the secondary flow passage to separate the cells and the product in the culture solution from each other, in which, in the separation step, in a case where a difference in pressure between both ends of the primary flow passage on a supply side and a discharge side during the feeding of the culture solution is denoted as ΔP [Pa], a membrane resistance of the hollow fiber membrane is denoted as r, and a flow passage resistance of the secondary flow passage is denoted as R, ΔP/2(r + R) during the feeding of the culture solution is 0.0005 mL/min or less.
