An object of the present invention is to provide a separation substrate having a high megakaryocyte blocking rate and a high platelet permeation rate, and a cell separation filter and a method for producing a platelet which use the same. The separation substrate of the present invention is a separation substrate including non-woven fabric for separating a platelet from a cell suspension containing a megakaryocyte and the platelet, in which an average pore diameter of the separation substrate is 2.0 &#x3bc;m to 15.0 &#x3bc;m, and a thickness of the separation substrate is 10 &#x3bc;m to 500 &#x3bc;m.

The present disclosure provides a membrane separation method of a cell suspension which can appropriately separate cells from debris, and a cell culture device. That is, membrane separation processing of the cell suspension is performed using a filtration membrane which includes an inlet-side opening formed on one surface and an outlet-side opening, which is formed on the other surface and communicates with the inlet-side opening, and in which the inlet-side opening and the outlet-side opening are disposed at positions deviated in a direction parallel to the surfaces of the membrane.
