To provide an electrophoretic chip more relaxed in the restriction of an observation condition than before.
An electrophoretic panel 10 is constituted so as to subject a dielectric substance to electrophoresis by applying an electric field formed by AC voltage to a sample containing the dielectric substance and equipped with a migration lane 3 for subjecting the dielectric substance to electrophoresis and a migration electrode array 6 composed of a plurality of migration electrodes 6a crossing the migration lane 3 and applying AC voltage in order to apply the electric field to the sample injected in the migration lane 3 to subject the dielectric substance to electrophoresis. The migration lane 3 is characterized in that the opposed surface to the migration electrode array 6 of the migration lane 3 at least in a part of a region where the migration lane 3 and the migration electrode array 6 are superposed one upon another is transparent. The migration electrode array 6 is characterized in that at least a part of the migration electrode 6a of the part superposed on the transparent region in the migration lane 3 is formed of a transparent electrode.
