The present invention provides a method for capturing specific cells (e.g. many types of cancer cells, including cancer cells not expressing EpCAM), and a method for analysis of specific cells involving the method. Included is a method for capturing specific cells present in blood or biological fluid, the method including: agglutinating blood cells in sampled blood or biological fluid; centrifuging the resulting blood or biological fluid; and then capturing specific cells therefrom onto a hydrophilic polymer layer.
