CHIP FOR SAMPLE LIQUID SUCTION DEVICE, SAMPLE LIQUID SUCTION DEVICE AND BIO-COMPONENT MEASURING SYSTEM

PROBLEM TO BE SOLVED: To provide a chip 10 constituted so as to suppress a rise in the pressure in a suction flow channel at the time of beginning of suction to prevent the erroneous detection of the clogging or the like of the suction flow channel in a case of employing a method for detecting the clogging or the like of the suction flow channel on the basis of the change ratio of the pressure in the suction flow channel at the time of suction of a sample liquid and to also provide a sample liquid suction device and a bio-component measuring system both of which are made efficient by providing the chip 10. SOLUTION: Since a rise in the pressure in the suction flow channel at the time of beginning of suction is suppressed if the chip 10, of which the small hole part for sucking the sample liquid has hydrophilicity, is used, the sample liquid is sucked without erroneously detecting the clogging or suction failure of the flow channel. Further, the sample liquid suction device and the bio-component measuring system both of which are equipped with the chip 10 are improved in efficiency because the suction of the sample liquid is determined accurately.
