A reservoir member is made of an elastic resin material. Additional reservoirs formed of through-holes are provided to the reservoir member at positions corresponding to reservoirs of an electrophoretic member. The surface of the reservoir member to be tightly attached to the electrophoretic member is formed flat. The reservoir member is tightly attached to the electrophoretic member without using any adhesive in such a way that the reservoirs align with the additional reservoirs. Thus, the capacities of the respective reservoirs can be increased. Since the electrophoretic member can be easily separated from the reservoir member, the reservoirs and additional reservoirs can be cleaned easily after the analysis, thereby reducing cross-contamination in samples.
