Abstract

A biochemical analysis unit comprises a base plate, which has a plurality of holes and is constituted of a material having radiation attenuating properties and/or light attenuating properties, and a porous adsorptive material, which is filled in each of the plurality of the holes of the base plate and forms each of a plurality of adsorptive regions. The porous adsorptive material, which forms each of the plurality of the adsorptive regions, has a pore diameter falling within the range of 1 μm to 10 μm. The porous adsorptive material may take on the form of a film.
