MICROCHANNEL AND ANALYZING DEVICE

摘要

A microchannel 4 for transporting a specimen S using capillary phenomenon includes an analysis chamber 6 having a cross-sectional area larger than those of portions located in front of and behind the analysis chamber 6 in the direction of flow, an inflow opening 5 through which the specimen S flows into the analysis chamber 6, and a discharge portion 7 through which the specimen S is discharged from the analysis chamber 6. The discharge portion 7 includes a pair of discharge openings 71a and 71b located opposite to each other with respect to the inflow opening 5. With this structure, impairment of transport of the specimen S due to the presence of a residual air bubble is avoided.
