Abstract
A light detection device includes a flow channel array that is arranged with axes of a plurality of tubes in parallel to each other and constituting a flow channel plane. A light source emits light so that an oscillation direction of an electric field component of the light is parallel to the flow channel plane. An optical axis of the light is included in the flow channel plane, and the optical axis forms a predetermined angle θwith respect to a direction orthogonal to the axes of the plurality of tubes on the flow channel plane, and a light detection system detects light emission from the plurality of tubes.
