PROBLEM TO BE SOLVED: To remove solid constituents in a sample liquid that is advantageous in terms of costs without increasing measurement time so much. SOLUTION: An analysis tool Y comprises a liquid inlet 61; one or a plurality of channels 51 for moving a sample liquid S that is introduced from the liquid inlet 6; and a separation film 8 for filtering the sample liquid S supplied to the liquid inlet 61 for introducing to one or a plurality of channels 51. The sample liquid S is allowed to advance in the thickness direction of the separation film 8 to filter the sample liquid S. Additionally, the analysis tool Y is preferably composed so that it moves the sample liquid S by capillary action in one or a plurality of channels 51. The sample liquid S is for example blood. In this case, the separation film 8 is composed so that it separates blood cell constituents in the blood. Further, the separation film 8 is preferably arranged at a higher position than one or a plurality of channels 51. COPYRIGHT: (C)2004,JPO
