A sample preparation apparatus, comprising: a first receiving part configured to accept a pipette and to receive a sample discharged from the pipette; a second receiving part (220, S1) disposed at a position separate from the first receiving part in the plane of view; a filter part configured to retain cells to be analyzed within the second receiving part (220, S1); characterised in that: the filter part is arranged to intervene between the second receiving part (220, S1) and a third receiving part; so that the third receiving part is disposed opposite the second receiving part (220, S1), a flow path configured to connect the first receiving part and the second receiving part (220, S1); a first moving means arranged to apply pressure so as to move the sample that has been received at the first receiving part to the filter part through the flow path and the second receiving part (220, S1), and move the components other than the cells to be analyzed to the third receiving part through the filter part; and a second moving means arranged to apply pressure so as to move the cells to be analyzed in the second receiving part (220, S1) from the second receiving part (220, S1) to the first receiving part through the flow path. a first receiving part configured to accept a pipette and to receive a sample discharged from the pipette; a second receiving part (220, S1) disposed at a position separate from the first receiving part in the plane of view; a filter part configured to retain cells to be analyzed within the second receiving part (220, S1); characterised in that: the filter part is arranged to intervene between the second receiving part (220, S1) and a third receiving part; so that the third receiving part is disposed opposite the second receiving part (220, S1), a flow path configured to connect the first receiving part and the second receiving part (220, S1); a first moving means arranged to apply pressure so as to move the sample that has been received at the first receiving part to the filter part through the flow path and the second receiving part (220, S1), and move the components other than the cells to be analyzed to the third receiving part through the filter part; and a second moving means arranged to apply pressure so as to move the cells to be analyzed in the second receiving part (220, S1) from the second receiving part (220, S1) to the first receiving part through the flow path. the filter part is arranged to intervene between the second receiving part (220, S1) and a third receiving part; so that the third receiving part is disposed opposite the second receiving part (220, S1), a flow path configured to connect the first receiving part and the second receiving part (220, S1); a first moving means arranged to apply pressure so as to move the sample that has been received at the first receiving part to the filter part through the flow path and the second receiving part (220, S1), and move the components other than the cells to be analyzed to the third receiving part through the filter part; and a second moving means arranged to apply pressure so as to move the cells to be analyzed in the second receiving part (220, S1) from the second receiving part (220, S1) to the first receiving part through the flow path.
