PROBLEM TO BE SOLVED: To provide an inspection chip for reducing dispersion of a component ratio of an analyte or reagent to be supplied to each measurement part.SOLUTION: An inspection chip 2 includes a main channel 119 through which an analyte 17 flows. Branch channels 160A to 160D are disposed on the downstream side of the main channel 119. The branch channels 160A to 160D include branch channel openings 161A to 161D opened in the formation direction of the main channel. The branch channels 160A to 160D are connected to measurement parts 170A to 170D. In the main channel formation direction, the area ratio of the cross sections of the branch channel openings 161A to 161D projected to the cross section of the main channel 119 or the area ratio of projection cross sections as the cross sections of the branch channel openings 161A to 161D projected to an enlarged cross section in which the cross section of the main channel 119 is concentrically enlarged is based on the quantity of the analyte 17 necessary for the measurement of each measurement part. |
