Abstract
A flow path plate for analysis of a component in a liquid sample, flowing within the flow path plate, by irradiating the liquid sample with measurement light is provided. The flow path plate includes a plate body having transparency; a flow path formed within the plate body and through which the liquid sample passes; a chamber provided in a part of the flow path and formed by a space having a cross-sectional area greater than cross-sectional areas of other parts of the flow path; and an internal part for detection disposed in the chamber and having a through hole. The through hole has an inner wall surface and constitutes a part of the flow path. The measurement light passes through the through hole. The internal part is configured to inhibit transmission of the measurement light from the inner wall surface of the through hole to the outside.
