A mask has a plurality of holes formed at positions corresponding to positions of a plurality of electrode portions on one surface of an object to be processed to mount thereon conductive particles , and the plurality of holes are opposite to the plurality of electrode portions formed on the object to be processed. A table has a plurality of holes for sucking the object to be processed from the other surface of the object to be processed , and for sucking the particles through the plurality of holes in the mask so that the particles may be mounted on the electrode portions formed on the object to be processed . A hopper contains therein the plurality of conductive particles , prevents the plurality of conductive particles from adhering to each other, and has a slit portion for dropping the plurality of conductive particles by the self-weight. A slit portion in the hopper is moved, facing the upper surface of the mask with a gap between the slit portion and the upper surface of the mask larger than a diameter of the particle , and the hopper is arranged in the front side in the moving direction, and the unit is arranged in the rear side, and the particles not dropped into the holes of the mask being collected by the collecting unit

A method for evaluating an artificial receptor includes subjecting a functional monomer and a crosslinker in the presence of a template substance in a vessel into polymerization, thereby forming a resultant polymer with the template substance usually in the form of a thin film, dissociating the template substance from the polymer and removing it from the vessel by washing an inside of the vessel, thereby to prepare an artificial receptor, feeding a solution of the same or different template substance into the vessel to associate the template substance with the resulting polymer; then determining the amount of the template substance remaining in the vessel, and evaluating the artificial receptor on the basis of a determination result.
