A micro-channel chip for concentrating nucleated red blood cells has an inlet-side channel, an outlet-side channel, and a separation narrow channel provided between the inlet-side channel and the outlet-side channel. The separation narrow channel has an inner wall having a dimension through which non-nucleated red blood cells easily pass and nucleated red blood cells hardly pass, and has a means for deforming or moving part of the inner wall of the channel to have a dimension through which nucleated red blood cells easily pass. The following are also provided: a method for collecting a liquid in which nucleated red blood cells obtained by using this chip are concentrated; and a micro-channel chip for concentrating particulates other than for concentrating nucleated red blood cells.
