(57) [Summary] [PROBLEMS] Using a sample solution dropping type biosensor, A method for measuring a sample solution that enables simultaneous measurement of a plurality of sample solutions, thereby speeding up the measurement and eliminating the influence of the change of the sample over time and the change of the measurement environment on the measurement. A biosensor suitably used for the measurement method is provided. A method for measuring a substance to be measured in a sample solution using a biosensor, comprising: a plurality of electrode sets each including a working electrode having a counter electrode and a biocatalyst in the vicinity; and each electrode set on the electrode set The biosensor using a measurement system having at least one biosensor having cells each separately forming a sample solution holding unit and a measurement device to which the plurality of electrode sets are connected so as to be used simultaneously. A plurality of the same or different sample solutions are simultaneously supplied to the respective sample solution holding sections, and the measurement target substances in the plurality of sample solutions are simultaneously measured. |
