Abstract
A flow channel structure includes a substrate including a supply flow channel that guides a measurement target liquid toward inside; a separation element accommodating unit that accommodates a separation element that separates components included in the measurement target liquid; and a detection unit that guides the measurement target liquid passing through the separation element accommodating unit, wherein measuring light for measuring information about the components is to be irradiated onto the measurement target liquid. The detection unit includes a measurement flow channel part that guides the measurement target liquid, an incident part that is provided at an end of the measurement flow channel part and that guides the measuring light toward inside the measurement flow channel part, and an emission part that is provided at the other end of the measurement flow channel part and that derives the measuring light from the measurement flow channel part.
