Light shielding portions are provided along a flow path on a top surface of a plate substrate at both sides, that is, an X1 side (right side) and an X2 side (left side) of the flow path. Then, when a fluorescent intensity is measured to determine whether a test sample reacts or not, a small amount of light emitted from the plate substrate and a lid body is also properly shielded by the light shielding portions, so that the stability of measuring the fluorescent intensity with respect to beads arranged inside the flow path can be improved. |
