The present invention relates to a method of adjusting a flow rate sensor 52 for measuring a travel time of a sample passing through a resistive body. The flow rate sensor 52 includes a straight tube 56, and plural photo sensors 52A to 52E for detecting interfaces 82A, 82B between a gas 80 and a liquid 81 traveling in the straight tube 56. Respective positions of the plural photo sensors 52A to 52E are adjusted by detecting the interfaces 82A, 82B by using such photo sensors 52A to 52E.
