Provided is a configuration of feeder wirings for electrodes provided for reaction regions arranged in multiplicity on a disk-shaped substrate. Feeder wirings extended from a current passing portion (U) provided at a central portion of a substrate (A) to electrodes provided in reaction regions (R) arranged in multiplicity on the substrate so as to be fields for interactions between substances are each composed of a first wiring (1) led out from the current passing portion (U) toward the outer circumference of the substrate, a second wiring (2) branched from the first wiring, and a third wiring (3) branched further from the second wiring, and a voltage is impressed on the electrodes from the current passing portion (U) through the feeding wirings (1, 2, 3), to develop an electric field in the reaction regions (R). |
