PROBLEM TO BE SOLVED: To provide a cell segregation chip and a method of manufacturing a cell segregation chip which is easily manufactured and capable of highly reliable diagnosis.SOLUTION: First, a pattern of fine flow passages is formed on a wafer (step S11). Then, PDMS (polydimethylsiloxane) containing magnetic particles is applied on the wafer where the flow passage pattern has been formed by using a spin coating method, that is, by using a spin coater (step S12). Then, PDMS containing the magnetic particles which have been applied on the wafer is solidified (step S13). Then, a PDMS layer is additionally formed on the solidified PDMS containing magnetic particles (step S14). Then, two layers of the solidified PDMS, that is, members are removed from the wafer (step S15). Then, a glass substrate is laminated on the member 2 such that fine flow passages are formed (step S16). |
