To provide an electrode plate for electrochemical measurements that enables detecting and quantifying the concentration of a target substance contained in a sample solution with rapidity and favorable sensitivity using an apparatus for electrochemical measurements is objected to. Specifically, the present invention is directed to a method of the determination using an electrode plate for electrochemical measurements 1 including a substrate 31, an upper layer 40 provided on the upper face of the substrate, a lower layer 11 provided on the lower face of the substrate, a first electrode body 32 sandwiched between the upper face of the substrate and the upper layer, and a second electrode body 12 sandwiched between the lower face of the substrate and the lower layer, wherein: the upper layer has a plurality of upper layer through-holes 41a and 41b; the first electrode body has a plurality of first electrodes 32d including a portion exposed from the upper face of the upper layer via the upper layer through-hole 41b; the substrate has a plurality of substrate through-holes 33; and the second electrode body has a plurality of second electrodes 12d including a portion exposed from the upper face of the upper layer via the upper layer through-hole 41a and the substrate through-hole in the second electrode body.
