1. A particle content extraction device, comprising: a first extracting unit, configured to extract, from a whole sample containing a target particle, an extraction sample containing the target particle without performing abort processing; a second extracting unit, configured to subject the extraction sample to the abort processing and to extract the target particle; and a stirring unit, arranged in a flow path between the first extracting unit and the second extracting unit and configured to vary a particle interval in the extraction sample extracted from the first extracting unit, and the stirring unit comprises a tubular member connected to a pump to provide the extraction sample to the second extracting unit.
