Abstract

A microfluidic device includes: a base plate allowing an electromagnetic wave to pass therethrough and having no autofluorescence; a microwell array formed on the base plate and including a wall layer in which a plurality of through-holes are formed in a thickness direction; and a lid member disposed opposite to the base plate in a state of being separated from the wall layer, wherein microwells are formed by the base plate and the through-holes formed in the wall layer, and wherein the wall layer is formed of a material containing a colored component that absorbs an electromagnetic wave of a predetermined wavelength.
